Description Bernhard 2024-03-08 03:23:04 UTC 
SUMMARY
If the SDR Color Intensity is changed the colors on screen don't change until SDR Brightness is also changed.
I've tried to determine if this is a problem with kscreen or the kcm, but I can't figure out what the kscreen option is to set it manually, if there even is one...

For what it's worth, it worked for me back when I used qt6.7 on some plasma 6.0 beta.

core/colorspace: fix ColorDescription comparisons

They used the sdr gamut wideness (which should've been removed) instead of
the sdr colorimetry
