I have seen burn-in on some older TFTs at least (mostly because
screensavers failed to blank, so the clock burned itself in). Those
were not terribly old (5-7y maybe?), but certainly not LED. I'm totally
fine with blanking measured in hours and that seems like a good
workaround.
I also like the dimming idea. It sounds to me like there could be some
filter be applied to the output of X...
Kind regards
