Sometimes occasionally but they’re probably never going to be cheap. Too hard/expensive to manufacture which is why folks like Samsung keep trying really hard with quantum dot LED panels.
That being said, I regret nothing about purchasing my LG C9 OLED TV a couple years ago. Works fantastic, looks fantastic and I pretty much never use the built in UI for anything by going to a Nvidia Shield for my content/streaming needs. I think the LG C series does an excellent job and it occasionally goes on sale during holidays/Black Friday.
