Question, I have an ATV 4K box latest gen with HDR10+ capability, I have a few movies in my iTunes library that offer HDR10+ but when I try to play them from my library it only plays in HDR10, The Thing digital copy for example, if I play it from watch now or continue watching in the ATV+ header it displays in HDR10+, anyone know why that happens?
Of course HDR10+ is available, my OP stated it plays in HDR10+ when starting movie from continue watching, tags only HDR10 though when playing from my library.
