SUMMARY
I am using the vk hdr layer and wine wayland to play games in HDR, e.g. Dead
Island 2. After installting kde 6.2 with kwin 6.2 hdr does not work as expected
anymore in Dead Island 2. The whites don't get bright anymore (super visible
in the games hdr settings page where you e.g. set the max nits of your display)
STEPS TO REPRODUCE
1. Enable hdr
2. Play a game with hdr (vk hdr layer + wine wayland)
3. HDR looks incorrect
OBSERVED RESULT
HDR looks incorrect
EXPECTED RESULT
HDR looks fine like it does in 6.1.5.2

ADDITIONAL INFORMATION
Moving back from kwin 6.2.0 to kwin 6.1.5.2 fixes the issue.
In addition something seems to have changed for the sdr brightness part when
operating in hdr mode. I have to somehow double the brightness of the sdr part
to reach what i got before.
Thx !
