I just checked Netflix and though it's listed as Ultra HD 4K on my AppleTV, it didn't play back in that format. Furthermore, the opening text was missing. I switched back to iTunes and the Dolby Vision light came on my LG OLED and the opening text was present.Just to add to the overall opening text problem, when I observed it at my friend’s place, her tv was standard HD with no HDR (it’s quite a few years old) and it wasn’t from iTunes. It was either Netflix or HBOGo. So the no text problem is evident outside of the iTunes variations.
