t is all about using the TV with some common sense and I have never had any issues with OLED TVs I have tested here, including our long-term test models. The AVForums team all own LG OLED TVs and gaming is a big part of use for Mark Botwright, who reports no issues at all with his B7 when it comes to retention.
As long as you are aware of the risk of excessive use of static images in bright picture modes and you use some common sense and the technology included to mitigate any issues, you shouldn’t have any problems gaming or watching static content with the B8. In terms of actual burn-in and damage to the screen, I have personally only ever seen it once and that was with an early panel used at a trade show, displaying the same static company logo for 24hrs a day during the event. I have never seen it with a domestic TV used normally in a home, so we can conclude it is very unlikely to ever happen in normal circumstances with a TV like the LG B8.
