My personal experience with LG C8 left me with MASSIVE burnin from playing Diablo 2, Path of Exile, and Diablo 4 for around 2.5k hours over a couple years. The skill bar and health globes and buff icons were all burned in and were glaringly obvious on any screen that had solid colors on the bottom quarter of the screen. Like a mess of gray circles and squares everywhere. It was enough that I went with Micro QLED for my newest tv and I will never worry about burnin again.
