I suspect we agree more than disagree. I was on the Driver/TCON development side. I remember the QD guys demoing new OLED TVs at DisplayWeek '17 that showed visible degradation of extreme (B&W bars and Logos) visible at 64 sRGB (10min B/W 1min Grey) during the show after ~72-96hrs. At show setup it was invisible and by the end of the show it looked terrible. You could swap the cables between TVs for comparison. Similar to standard definitions of Mura a method of defining visible burn-in, you'd have to define the burn image (16pix B&W block or CNN Logo?), the detection image (64 Grey?), viewing distance (30deg FoV?), and visible contrast (+/4 MND?). I guarantee you all the OEMs have a spec. Here's a set of modern 20hr/day tests at 6 months (posted above) where OLED has visible degradation (mostly Sony/Viso but also Samsung and LG). The new ones are definitely better! https://www.rtings.com/tv/tests/longevity-burn-in-test-updates-and-results https://www.rtings.com/tv/tests/longevity-burn-in-test-updat...
