I have a 65" LG OLED, now about 4 years old.
The picture is simply brilliant, particularly with 4k stream programming.
But burn-in is a REAL problem.
We now have both 7 and 9 logo's etched into the bottom right of the screen due their constant channel branding which is totally unnecessary.
This annoys me immensely

(7 and 9 should have class actions taken against them...I wonder how many TV's they've buggered
up due this avoidable practice)
