Size or Picture quality

I can’t decide;

55 inch LG C6
65 inch Samsung QN90F

Their prices are really close in my country, the distance between my eyes and screen will be 220cm, going to watch movies in a purely dark room most of the time, which one would you go for? Is it worth going for OLED even if its smaller? My budget can’t help me buying 65 inch OLED 🥲
