I just swapped out my ~5 year old LG C9 for a new LG C3 due to a slight amount of burn in. It was in the center of the screen and while nobody else could see it I could.
It’s also our main TV.
For gaming it’s amazing, incredibly low latency and the pixel smudging from poor pixel response rate is gone, so it’s more like a CRT in that respect.
