Like all OLEDs regardless of model and manufacture BURN IN can be a problem. Burn in can occur of the TV is frozen on an image, a logo or icon on the screen say like CNN, Ticker tape at the bottom of most financial station, burn in can also occur when a repetitive scene is repeated tirelessly.
“Pixel shift” should only be performed once a year and your results may vary, you may still have a lighter version of burn in or discoloration.
so in order to combat Burn in avoid those scenarios above really at all costs. Rather than freeze a netflix movie to go have dinner- just turn the entire TV off for example.
Lastly and Im not a big fan of them but I would buy the extended warranty and hops the manufacturer replaces your TV with a new one.
Or buy a Samsung full array QLED or a sony 900F and not have to worry about it, not quite as nice of picture but pretty nice overall.
