Do those people use it solely for gaming and nothing else? Games with HUDS prominent on screen?
That's me. I've completed the last 3 Assasins creed games on my LG C9, played each one in HDR and all of these games feature the exact same HUD design and it's in the same location. No burn in yet. I've also completed dozens of other games which have their own HUDs and no burn in after 4200 hours
