OLED is fantastic when the colour of the movie or TV or Gaming program is good but there are some issues I have noticed over the past 2 months since I got my C1 65" Oled , First of all Dolby Vision seems to give the best colours

Steam , Amazon prime backgrounds will make your screen look bad , On the steam background I get these odd lines shooting up my screen in the lower part of the menus , Dont get this on anything else so my guess is the way the steam app background is made , Amazon prime background is not black so you get this odd grey colouring that can look different . example looks like the TV screen has light bleed when it doesnt..... I've tested my screen a lot and on the right movies the colours are perfect but a few look bad , prime exmaple is the first 3 mins of the Green Knight look terrible when he is walking through the dark hall ways , this should all look black but because of the way its filmed the blacks look like a green washed out black instead. Anyway just be aware there are some little issues , look up Greyscale and you will see what I mean , OLED tech isnt perfect.
