The TV dims the highlights very agressively (on SDR picture) especially in darker scenes or with a small logo or text on screen with black background. It doesn't just dim the backlight, but does other things to the picture aswell and this completely ruins and crushes the highlights. It makes all whites grey and some highlights even get "burned", meaning smooth highlight gradients of low->medium->high brightness get converted to a medium->low->high gradient so there is this darker artifact in the middle of the gradient. Opening the TV menu on pretty much turns the picture back to normal with bright highlights etc, goes back to ***** when I close the menu.
Couple of pictures to show the problems in the "highlights". I've read reviews stating the highlights are a little dim on the TV but that is a gross understatement and it's not just that. I have checked the videos on another display and they look normal. Can someone test on their QLED-set if its the same as mine?
