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...
