It's an interesting video thanks for posting it and I do get that it is mostly HDR that benefits from this increased brightness in order to attain realistic scenes. However I do certainly think there is a definite subjective and personal element to it and an OLED with HDR maxed in a dim room is at my personal comfort limit and still look amazing to my eyes. I think that LED technology in general has really put me off bright displays due to the glare I got and maybe only Micro LED will change my mind on this in future if it is easy on the eyes as OLED.Did you watch this videoquite interesting.
