drm_info output
DESCRIPTION
SDR applications and content look very much de-saturated after the 6.7.0 plasma
update. Also the sRGB saturation slider does nothing. HDR content works (I
tried an HDR blu-ray with mpv).
STEPS TO REPRODUCE
1. Update to 6.7.0
OBSERVED RESULT
Whole UI becomes de-saturated.
EXPECTED RESULT
Normal SDR saturation and sRGB saturation slider
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.7.0
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 7.0.12-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor

ADDITIONAL INFORMATION
A similar thing happened back in the transition from 6.3.5 to 6.4.0 #505857
with Kwin "not being able to parse the display primaries". I'll attach the
output of `kscreen-doctor -o` and `drm_info` to maybe help.
