> unable to stream HD Content to my iPhone

Yeah this has been the case since forever. It prioritizes instant playback vs forcing 1080p or similar.

Can't speak for iPhone, but on iPad, I've moved to using the website which goes goes to 1080p immediately.

> still have to download it, to see it an acceptable quality

Downloaded content do contain a whole lot more compression than streaming at max phone supported quality, so just a tiny FYI.
