Yeah, that is my problem. I have calibrated my new TV to meet optimal color and light levels - and it looks absolutely great in like 96% of all I've thrown at it.
But watching See last night was a nightmare. And I know AppleTV+ can look good, as I just finished watching Silo, and even though that by design is also a quite dark show, I never lost sight of what was going on.
I guess there's not much to do other than turn up the brightness. Which shouldn't be necessary. But alas, the world is not perfect.
I can assure you it's not the TV :-)
