I have a Sony tv and when I’m watching tv or playing a game the picture is perfect, but when I watch a streaming service, like Hulu, Netflix, or Disney plus, it seems as if the tv attempts to brighten up the darker areas and it leads to the darker parts of the movie being almost too dark/whitewashed to see. I’ve poked around in the tv and in-app settings and I haven’t been able to find anything that fixes or reduces my issue. Any help would be greatly appreciated!
Your tv needs to be calibrated.
It's probably not bright enough for HDR to look "proper" and is overcompensating in other ways.
Turn on some HDR tuning guide, and get your blacks looking perfect and try the scene you're having issues with again.
