I’m not a Samsung fan lately. I would tell you to get an oled. They probably get much brighter than the 1080p tv you are replacing so it shouldn’t be an issue. I have sun that directly shines on my oled for a couple hours a day it doesn’t cause issues. But since you are not, I wouldn’t worry too much about Dolby vision or hdr10+. I’m not 100% sure if the Apple TV will switch to hdr10 in iTunes but I think it does. I’m pretty sure Netflix does. Maybe somebody can correct me on that. So buy what looks the best to you. That is what is most important. If you buy a “lesser” tv in your mind it will always be a “lesser” tv to you.
