Kram, have you tried to use custom timings on the DW based on CVT-RBv2 ? I'm curious if tightening the refresh parameters and removing blank cycle may have an effect on that flickering you've been showing in that video.It is OLED property that's too organic to emit steady light at the start of each frame. There is oscillation happening. Or it doesn't have involuntary/general PWM behavior in a short period enough to cause eye strain.
Eyes cannot stare at a flickering monitor at just average 200nits brightness for long.
I have said it somewhere before.
