I recently received a Chromecast Ultra for free and decided to play music ( KEXP) from YouTube on the ultra. The image looks a lot better than when streaming from my Sony XBR X 900E with Android TV. Why is this? I can't go back to the Android TV after seeing this. Will nvidia shield give me similar results as the chromecast ultra? Because I like having the menu from the tv w remote available. Does it have something to do with vp9.2?

Thanks for any help!
