Yes OLED is expensive and still needs time for competition to settle... But I think this is the real leap forward away from the LCD era but it's not quite mature enough or affordable enough yet. And I don't really see them very often to be honest and I know a lot of different models of various sets because I put them up regularly.

Just get an LED lit LCD display like the ones you posted then. it's still much better than standard LCD which is side lit.

I have come across a 80" sharp that melted in a container whilst shipping that looked like one of those new curved OLED screens :) Still worked too even though it was shaped a bit like a banana.
