I allready had a rant here:

The whole thread maybe interesting to you.
It was. Everything you said made sense. I've used GIMP for years and like it a lot. However I get better colors out of darktable than
dcraw. As I understand it, UFRaw calls
dcraw from inside GIMP.
In that thread, you said:
And for archiving I use Shotwell.
Do you have a color managed version of Shotwell, or does color management not matter to you? Last I tried, Shotwell could not read ICC profiles. Nor could Pix.
The Z6 and Z7 look like great cameras! Judging by DPreview's studio comparison widget, it looks like the Z6 has less high ISO noise than any other 135 camera.
OK, I studied it a bit more.
Downloaded the software to define colorbalance, and I see my Dell really has a Sharp (Corporation;--)) monitor with a whitepoint of 6500 degK. I should not put deg there, Celsius, Fahrenheit and Rankine need a deg(sign) Kelvin not, as per ISO. But we are talking temperature of radiating black bodies here.
I can switch to another profile with whitepoint 5000 K. And indeed I get much more saturated colors, almost garish I would say. Makes me think of the Fujichrome Velvia film. In all programs including Shotwell. So it has colormanagement when using ubuntu, and probably all Debian derived linuxes as OS.
There must be more to it then just temperature, these profiles are 1,7 kB en 12 kB (for the velvia one).
I see the famous gamut pictures. Had those in university, but I forgot all about it. Need some more studying but it looks like the larger envelope is what my screen announces it can do, and the inner triangle what the profile uses of it. As you see the 5000K one begins to be slightly out of bounds. And red and green gain most terrain just like in Velvia film.

Whitepoint 6500K

5000K
So I need to check if my desktop PC with a Samsung display has a 6500 K profile. It actually has a number, so apparently different profiles can lead to the same whitepoint.
Prints, if any, I mail to a printshop. They ask nothing, may look at the exif, and they are just beautiful. Do not change a winning team.
The camera's have lot of whitebalance adjustment stuff, but automatic has served me well sofar. I only change defaults when it matters, and I know what I am doing.
If I send .jpg's to somebody else, it is up to them. The only complaints I get are about messy hair or raccoon eyes. Or too many pixels.
Yes the Z6/7 are great, you can study lenssharpness in the extreme. But in the end nobody has an 8K monitor yet, there is one 5K one now. Or needs an 8K print at 300 dpi. Then, suddenly you see a little bird in a landscape you never saw with the naked eye. And can still crop it out. I need to crop a lot anyway because Nikon is already 5 months promising a 70-200 mm and I paid in full. Maybe that should be spelled paid in fool? The longest Z lens is now 85 mm, and I have it. Not going to buy any Nikon stuff untill I got that zoom.
And you are right the Z6 works great at dinnerparties. A few candles is already enough. Just before corona broke out I noticed restaurants here are dimming their lights very slowly during the progress of the dinner. And I need to open up more and more.
