The K3 III in the comparison tool

With exiftool -xmp -b, I see the same things as you on the Z9 and K3III RAW files from the DPR studio scene.

Darktable can't open the .NEF of Z9 at all (not supported yet).

RawTherapee can but I couldn't see anything related to those ACR settings.

But if I run same exiftool command on one of my DNG files from K3III, there is nothing output - so I think it means the XMP information from ACR really is embedded in the RAW files from the studio scene.

Yes, in the DNG files we can download from DP for the Pentax cameras we can see the embedded XMP files. We even can see what programs DP do use and how often the file was opened.

But for the Z9, we see not the XPM from DP, we see the XMP file made from our PC's and on this way, so long we use not our own settings, the Z9 XMP show default setting.

The problem is now:

I know that DP use a sharpness of 0 for the Pentax cameras, do to the embedded XMP files in the DNG file, but what I do not know:

1.) is this ACR's default ? I got answers: yes it use 0 - and in an another answer: it's 25 like with your LR.

2.) do use DP only default settings, or do set DP for all camera brands the sharpness to 0 for a fair compare, independently what default setting the ACR would use for the cameras.

3.) same for the color noise: do set DP this setting to 0 (like it do for the Pentax cameras) for all cameras for a fair compare, or use it default settings (and here, for the Z9 ACR would use a little color noise NR as a default - as we could see in the XPM of our PC)

At last: LR is based on ACR (how much I do not know), therefore I think it is for me easier to compare a LR and ACR JPG of this downloaded files. For example the first picture, with the ACR XMP from DP the picture in the comparison tool looks very similar to that, I made with my LR with their ACR XMP settings.
