Video of showing calibration loading after clicking Calibrate HDR then cancel
DESCRIPTION
The HDR Calibration is not correctly loaded upon boot. I have a Samsung Odyssey
G7 G75F 40" and a Samsung S24A600NWU, both with HDR. Upon boot, the Odyssey is
far too dark and the other one far too bright (see attached video of the
Odyssey). I can then open the Display and Monitor settings, select "Calibrate
HDR Brightness..." and immediately click Cancel, which restores my old
calibration.
This was introduced only very recently - I believe with 6.8.0. I do not have
other HDR displays to test with.
STEPS TO REPRODUCE
1. Boot with the two calibrated HDR displays connected.
OBSERVED RESULT
The screens do not display with their calibration. I don't recall if this was
the HDR-enabled-but-no-calibration default, but I think so,
EXPECTED RESULT
Both screens display with their calibration loaded
