yes exactly.. even good 1080p source contents looks exactly like 4k. very good upscaling. Actually I don't know why people say that oled are best for dark rooms. Its brightness is is too much for my eyes in dark room even for normal contents (HDR is way more brighter). Due to this much brightness , I have to lower the oled light to 55 brightness to 50 and contrast 100 and it's still more than enough for me lol. I prefer watching it with sufficient lights. First time using oled after coming from 2011 Sony LCD and man its really day and night difference.
... and the sound is also very good for a TV , now I am confused whether to buy a soundbar or not LOL.
