Proper HDR for desktop is still very wip. They had two talks at XDC about what they had to do do to make it work with gamescope:
- The rainbow treasure map: advanced color management on Linux with AMD/Steam Deck - Melissa Wen
- Rainbow Frogs: HDR + Color Management in Gamescope/SteamOS - Joshua Ashton
Kwin has basic support for displaying HDR games through gamescope in KDE Plasma 6

Works fine in Gamescope. Doesn’t work in any desktop environment.

Plasma 6, to be released at the start of next year, will have support for HDR. Not sure about the specifics though
