Hi guys, I recently bought a 55 inch Sony XF90 in The Netherlands, and made a similar post in the r/bravia subreddit I have some questions Android TV that I hope some of you can answer:

Does the inbuilt chromecast support HDR? I've seen conflicting posts on this. I read somewhere that the inbuilt youtube app doesn't but if you cast youtube from your phone it does? But how can it if the chromecast doesn't even support HDR in the first place!

How do I enter or switch between the inbuilt chromecast and other apps? (I mean the chromecast mode with a changing background like it would appear if you had an ordinary chromecast). The inbuilt chromecast doesn't appear on my recents bar.

What apps DO support HDR? I know netflix does, and dolby vision looks AMAZING on it. But does amazon prime video, plex, kodi, youtube etc. as well?

Sorry if the questions are too long guys, but help would be appreciated! Thanks!
