I wonder if watching TV/movies on phones in bed at night is a normal use case. I thought it was a normal thing that many/most people do, but this comment suggests that perhaps my social circle is odd in that way.
I have an incredible TV. OLED with increased brightness, the latter being new tech. The combination of OLED and HDR is jaw dropping to witness. To me and to everybody that I show it to.
What do I show them? A Youtube list with TV demo videos that specifically demonstrate the effect. Deep blacks with locally bright highlights. Not to mention very deep vibrant colors.
I watch the demo videos every 2 months or so to remind myself that I have an awesome TV. Because I most certainly do not experience anything remotely like that on ordinary TV channels, streaming services, the like.
Streaming services absolutely have HDR programming. My GF has been incredibly impressed as a normie.
Probably more impressed than me because I consider OLED to be relatively meh for HDR. Not really bright enough for me, I only care about OLED largely for black depth / lack of glow and motion quality for games, I rarely watch TV/movies in comparison.
Hence my remark on OLED with increased brightness. In the TV world, they're called OLED.EXT panels. The new iPad Pro uses a different technique (layered panels) to achieve the same thing.
Infinitely deep blacks combined with high local brightness is god-like to experience.
The money I would give to have this in a form useful to me is beyond what most people would considerable reasonable. But god I want it.
Your GP and optometrist would certainly prefer you don't do it. I can't speak to the frequency of how much other people do it, but my wife and I try to avoid it, not always successfully.
