Thanks. I just read the article and it's interesting but I think it's old. I do believe that you can match the frame rate with the original source in AppleTV now, and it also supports Dolby Atmos. Unfortunately my Sonos doesn't which is a real bummer. The biggest issue for me is that I can upload a 4K video at 60 fps on Photos but it comes out terribly, with stuttering and looks terrible. It defeats the purpose of using 4K60 on the iPhone is you can't actually view it on a TV.
