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.
