Yeah seen that Linus video, it felt a bit of a money grab video tbf since they started off the video saying burn in is an issue and your OLED screen will last a year or 2 then slowly started to talk about features that can prevent it, then ran the full pixel refresh and pretty much fixed it.... albeit with some sharpness loss.
They did not really compare that sharpness loss in depth with picture comparisons for very long.
How come also VT burn in test, which appears more accurate since he uses 3 different channel for 20hrs for 6 months showed no burn in or sharpness loss

Its possible a more detailed image quality testing needs to be done from day 1 to 1 year etc, not sure anyone has done that to see OLED pixel degradation, maybe VT might consider it, id take his word other Linus or Rtings testing any day.
