Well I hope to mitigate potential burn in problems by careful management... no desktop icons or taskbar, screen turning off when idle and of course the included burn in protection with the monitor. Regular (enough) pixel cleaning will help too.
As for the brightness issue, I just don't get the problem. It can look and feel brighter than my old Samsung Odyssey G32 that was 1000 nits. Agreed that monitor didn't have full array local dimming but the contrast on the OLED monitor between light and dark just makes it appear so much brighter. I'm all up for brighter burn inless OLED's of the future but at the moment this class of 4k monitor (qd oleds included) are simply incredible for gaming and content consumption.
