I still own Pioneer Kuro that don't have image retention nor burn-in and I owned that set for just about 10 years. I also owned a Panasonic VT60 and that thing was IR/Burn-in mess. I just recently sold my VT60, I owned it for almost 6 years and even up to the day I sold it if I watch static images like the tiles on the Amazon Firestick, my Amazon Music app image would be on there for at least three days or more. I loved the picture quality of my VT60 but burn in and IR always bothered me. I had burn-in, (you could see it on a white back ground, very similar to what I'm seeing on pictures of OLED burn-in),long-term IR and regular IR on my Panasonic.
