It's rare period and you really have to have something static for days not hours. All settings to the extreme brightness etc.
With OLED Light cranked up to 80+, it seems to typically take ~300 hours of cumulative qualifying static element display do develope differential-aging-based burn-in, so days is correct (even over a week), but that is days of cumulative
display (not uninterrupted consecutive display).
On the ther hand, it is not correct that you need to have 'all settings to extreme brightness' - even with OLED Light set below 40 (130-150cd/m2 peak), qualifying static element display can cause burn once cumulative display times exceed ~1000 hours, so weeks, not days
In terms of 'qualifying staic elements', these are bright fully-saturated yellow/orange/red or green static display elements, and at this point, there are four classes that have been reported:
-CNN or MSNBC logos (most common cause)
-some game HUDs (red Zelda Hearts is one reported example)
-yellow subtitles (one report)
-yellow progress bar from media player (one report)
The burn-in test being run by Rtings.com is going to shed some light on this subject over the coming weeks.
Burn-in is a rare occurance for those who don't have qualifying viewing habits, but is appears that heavy CNN or MSNBC watchers are not going to be happy with the current generation of WOLED.
LG needs to up their game in this department or Samsung and their marketing prowess could mop the floor with them...
