Bug ID: 516881
Summary: HDR brightness and colour saturation significantly
reduced in 6.6.1
Classification: Plasma
Product: kwin
Version First 6.6.1
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

Target Milestone: ---
SUMMARY
HDR brightness and colour saturation significantly reduced in 6.6.1 compared to
6.6.0. Seems that with the removal of the ability to override the average
brightness, something has occurred that has made the brightness and colours
significantly worse than in 6.6.0
To ensure I was observing this correctly, I set the average brightness as the
EDID default of my monitor of 911.
STEPS TO REPRODUCE
1. Calibrate HDR in 6.6.1
2. view HDR content
3.
OBSERVED RESULT
very low brightness, low colour saturation
EXPECTED RESULT
appropriate HDR brightness levels, appropriate colour saturation
