Fedora 36 (KDE) colormgr get-devices is empty

[MalteFlender]

My system is a Fedora 36 with a NVIDIA RTX 3070 using the 515.57 driver and two DELL P2715Q screens connected via DispayPort. Here you can see all colord related packages:

PC:~ # rpm -qa | grep colord
colord-1.4.6-1.fc36.x86_64
colord-kde-0.5.0-16.fc36.x86_64
colord-libs-1.4.6-1.fc36.x86_64

Currently I am experiencing 3 probably related problems with my color management. Which I tried to address here too.

• On startup the colord.service shows a failed to get edid data: EDID length is too small error, which is strange because the nvidia-settings lets me export EDID as ASCII-Files for both screens and I can interpret them just fine, also a laptop does not show this error on one of the screens.
• The next problem is that, similar to this, I can't load any new .icm-profiles.
• And the biggest issue that colormgr get-devices only finds a printer, but no screen.

So I am unable to use color correction on my main operating system.

I've already tried to upgrade my system to the newest versions and reinstalled all color related packages as well as installed the gnome-color-manager to no success.

Do you have any idea as to what can cause such problems? Do you need any further information from me?
