enabling the built in color profile desaturates colors quite a bit and does some kind of perceived brightness to luminosity mapping that desaturates bright / dark hdr content even more

It maps the colors to be more correct, and it does use the brightness info from the EDID for HDR content, so that checks out.

I think there must be something wrong with my screen since the hdr reduces saturation more than anything else

It might enable some sort of gamut mapping on the display side... HDR on monitors is really weird sometimes.

Side note, when I turn off hdr only from kscreendoctor the display stays in hdr mode until it turns off and on again, that didn't happen with nvidia

I think that's a bug in amdgpu. It should force a modeset on hdr change, but it doesn't.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
