Summary: HDR support issues after updating to 6.4 from 6.3.5
Classification: Plasma
Product: KScreen
Version First 6.4.0
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: common

Target Milestone: ---
SUMMARY
When I did a full system (Arch) update to Plasma 6.4 and after rebooting SDR
content when using HDR for my monitor (AOC AG276QZD2) started looking washed
out. I did the HDR calibration but to no avail. the sRGB color intensity slider
had no effect (100% was exactly the same as 0%) while on 6.3.5 it had a pretty
big one. Also, from what I could see, HDR content also looked quite worse, but
I didn't confirm that. I reverted back to yesterday's (6.3.5) state (timeshift
is magic when it works) and it's a night and day difference for SDR, I still
didn't test HDR.
STEPS TO REPRODUCE
1. update to plasma 6.4 from 6.3.5
RESULT
SDR (and possibly HDR) looks worse than 6.3.5 even after spending lots of time
trying to calibrate and fix it.
EXPECTED RESULT
HDR looks better with all the new tools in the settings.

ADDITIONAL INFORMATION
Monitor is AOC AG276QZD2. I can attach even more info if it is needed, though,
I'd prefer if I didn't have to go back and forth on plasma versions. Also, this
might not be an issue of kscreen, but it seemed like the most sensible thing to
pin it on. Here is the list of all packages that were upgraded when going from
