I have 2 questions regarding casting the Vudu app.

1) Airplay to the ATV4 - I know that when you use Airplay, the iOS device is basically passing off the stream and the ATV loads it directly. I also know that not every movie/tv show is available in HDX on iOS. Does this mean that if I own a movie in HDX, but it's not available to stream on iOS in HDX.....does Airplay stream it in HDX or SD?


2) Chromecast Ultra and iOS. Similar question. Obviously iOS can't do 4K. But if I own a 4K title, can I cast it via iOS to a Chromecast and the Chromecast will play it in 4K?
