If you’ve got the money go oled as there is no back light, each individual pixel is self lit. The contrast and brightness and the ability to see dark images in detail is the best of any screen technology.
They used to suffer with image burn in if you left the screen on a channel with a lot of static images (Sky Sports News for example) but newer screens have technology to combat that and I’ve had my LG oled since Jan 21 and it’s still like new. The screen is so bright when watching TV in the evenings I don’t bother with any other lighting in the front room.
OLED seems a bit beyond my budget, unfortunately.
