Same version here.
I have donloaded an iso file of windows 23H2 and will be doing a fresh install with that when I have the time. That is the surest way to fix the issues.

Windows 11 24H2 26100.2161 today; monitor profiling still broken

Could you share a shot of the window where the "automatically manage color for apps" would normally be seen?
I'm behind time on this, but I neglected to mention: I use DisplayPort, and haven't seen the issue.
In the Color Management control panel, I have removed al of the profiles except the one I wish to use. (Which doesn't delete them.)

Thanks. I'm mystified.
I have a single monitor, connected via DisplayPort.
What's your display adapter? Drivers?
I don't know if you'd care to go into the Registry Editor, but I get this:

As I understand the Registry here, you have Auto Color Management enabled with "1"? On my desktop, that key is set to "0".Thanks. I'm mystified.

I don't know if you'd care to go into the Registry Editor, but I get this:
I did notice an oddity today; I set one of the desktop's Windows installs to allow 120Hz and 10-bit color, after selecting "Use NVIDIA color settings." in the Nvidia Control Panel.
When I went back to the Color Management page, it had set the ACM to "On", so I had to disable it again.
I'm also on version 26100.2605, and this is the color management page I see:
I wonder what the difference is on Flycaster's machine that ACM setting isn't visible? As you say, graphics hardware, drivers? Or maybe some other setting removes it from visibility?

I'm not good at finding drivers and could use some direction, so I can report back. Also here's my Registry; data is the same for each. Any safe suggestions...I'm not too good at this. As for graphics, I'm using Gigabyte RTX-4060.As I understand the Registry here, you have Auto Color Management enabled with "1"? On my desktop, that key is set to "0".Thanks. I'm mystified.

If I'm reading the Registry correctly, Auto Color Management is enabled even if you can't see it.I'm not good at finding drivers and could use some direction, so I can report back.

Can you see the Nvidia control panel? This is what its System Information says for me:Any safe suggestions...I'm not too good at this. As for graphics, I'm using Gigabyte RTX-4060.
I think this Windows has the ordinary, Microsoft-provided driver; this install is too new for me to have done all the messing around I usually do over time.

Just checked to see if I can switch profiles within windows, I can`t.
But I can switch profiles using the Dell Software.

My Nvidia system info reads about the same, other than I have a Yes and you have a NO for Resizable BAR (whatever that means). So, you say that my ACM is enabled, but can't be seen. Isn't this unusual...can't be seen? As it may be enabled, I guess I'll just leave well enough alone. Lastly, the screen for Nvidia Control Panel>Dislplay>Change Resolution>Apply foloowing settings has "use default color settings" checked. Should I be using that or should I change it to "use Nvidia color settings?)If I'm reading the Registry correctly, Auto Color Management is enabled even if you can't see it.

I think it has mostly to do with gaming, and Yes is probably correct. This install is relatively new and un-tweaked.My Nvidia system info reads about the same, other than I have a Yes and you have a NO for Resizable BAR (whatever that means).If I'm reading the Registry correctly, Auto Color Management is enabled even if you can't see it.

I'm saying that if I understand the Registry correctly, it appears to me to be enabled; my ACM is disabled, and my AutoColorManagement Registry entry is "0" while yours looked to me to be "1" in your screen shot.
Yes, when in doubt I prefer to do nothing.
If you want to make any changes from the default settings (like I just did) I think "use Nvidia" would be necessary, but as far as how this all applies to ACM, I'm in the dark, hoping that the reason why you can't see the setting that BobKnDP and I can see but you can't, will reveal itself.
A lot of this is new to me, and I'm looking to learn myself. Copilot had nothing useful to say, and this Windows install doesn't have ChatGPT or Perplexity AI on it yet.
I'm hoping someone who knows will show up to clear the confusion.
Edit: I was wrong, this install does have Perplexity AI. This was considerably more than Copilot provided.
Here's what it says:
"There are a few potential reasons why you might not be seeing the Auto Color Management (ACM) setting in Windows 11 24H2:
- Hardware Requirements: ACM has specific hardware requirements. Your system needs to have:
- A WDDM driver version 3.0 or greater
- A supported GPU:
- AMD: RX 400 Series or later, or Ryzen processors with Radeon Graphics
- Intel: 12th Gen (Alder Lake) or later for integrated graphics, or DG1 or later for discrete graphics
- NVIDIA: GTX 10xx or later (Pascal+)1
- Display Settings Location: The location of the ACM setting has changed in recent builds. In Windows 11 build 26052 and later, you need to look for it under: Settings > System > Display > Color profile Instead of the previous location under "Advanced display"1.
- Windows Update: Ensure your system is fully updated. The ACM feature might not be available if you haven't installed the latest updates.
- HDR Status: If you have HDR enabled, the ACM setting might be hidden or reserved. ACM is automatically managed when HDR is active9.
- Color Depth: If your display supports 10+ bit color depth, Windows may already be managing colors for apps, making the ACM setting unnecessary9.
- Build Version: Confirm that you're actually running Windows 11 24H2. You can check this in Settings > System > About."

I've uncovered some additional funkiness.
I'm having trouble getting Photoshop (26.2.0) to run in 30 bit mode, unless automatic color management is enabled.
If I set the Registry keys to zero, toggling the nVidia color setting in the control panel set them back to 1.
I wish I understood this.

What I saw when I mentioned this previously:
"I did notice an oddity today; I set one of the desktop's Windows installs to allow 120Hz and 10-bit color, after selecting "Use NVIDIA color settings." in the Nvidia Control Panel.
When I went back to the Color Management page, it had set the ACM to "On", so I had to disable it again."
Except rather than the Registry setting, I saw the change on the CM page.
I was relaxing on a laptop this evening, but I just got curious and fired up the same desktop Windows install I was using this afternoon; "Nvidia color settings" is still selected, and the new Nvidia control panel settings of 120Hz and 10-bit are preserved even after ACM was disabled on the Windows Settings CM page. The Registry also has ACMEnable set to "0".
If anything is wrong, I haven't detected it yet. I don't use Photoshop, so can't check that. And I'll be careful not to toggle "Nvidia color settings" so as not to risk breaking something.
So do I. There's things going on behind the scenes that I don't see a reason for.

I now think that the toggling in the nVidia control panel only worked because it turned ACM back on.
If I diable ACM, no 30 bit color in PS. Turn it back on, and 30 bit is there again.
I switched the graphics card between 10 and 8 bit. It appears that I am getting real 10 bit (30 bit) color in Photoshop.
Stranger and stranger.

Unfortunately, my mind is having trouble coping with all this info. So, let me state my bottom line here: It appears that although I have made several profiles with my i1Display (updated,) when switching between these profiles, I am not seeing any changes. Therefore, I'd appreciate some guidance on the "correct" way (steps) to activate (set-up) these profiles? Thanks.
How are you "switching" profiles?
I go into the Color Management control panel. (That's the old control panel, not the more modern Windows 11 settings.)
I set the desired profile as default.
Actually, I remove all the others. That doesn't delete them, and they can be re-added at will.

This is what I have been doing: The same as you. But, as I set each one, by one to Default, I'm not seeing any change. Could it be that I have to reboot after selecting a default in order to see differences. I think I remember before I had to replace the motherboard (same as original,) by just selecting a profile, I'd see a difference???
Seeing a difference in what ?
The Windows desktop seems to not be color managed.
Setting a new profile to "default" doesn't seem to load it. One way to do that is to right click on the Windows desktop and click "refresh".

Returning to the original topic: yesterday, a Web search revealed a compatibility setting I hadn't noticed.
This is the application to Calibrite Profiler.
With it set, Profiler does not default to an sRBG gamut if Windows ACM is enabled.
It needs more testing, but this may be what I was looking for.

That looks like a good punt for some of you.Returning to the original topic: yesterday, a Web search revealed a compatibility setting I hadn't noticed.

Realised that when I first built this windows 11 Pc I was still using my old 13 year old monitor and that one calibrated fine, I could even change profiles within windows.
Since getting my new monitor I can no longer change profiles within window but I can through the monitors software.
I might see if I can update my old W10 system to the latest version of W11 using media creator, I`ll be turning that old system into a Nass at some point so nothing to loose. At least then, I will have something to compare against.
