I could not find this info in the AppleTV+ app of Apple support doc. Do the Apple shows and 4K movies playback in 4K on iMac? In previous macOS they do not. Please point me to the support doc if there is one Thank you!

not certainly on iMac 5K 2017 .. in video info it always list video quality as SD. weird enough to contemplate if its even doing HD. no way either to confirm bit rate yet!

They really should allow downloads. Internet as a whole in the US is still pretty bad. I get 500 Mbps with Spectrum but I still experience buffer and quality drops. Especially after work. Downloading games on Steam, I can usually hit 45 MB/s.

I'm not sure that really means anything, the HLS stream would downgrade to HD without affecting the URL if the license object isn't present.

apple never allowed 4k downloads earlier either. only HD .. probably sticking to same.
And that’s the point of my post above. The internet in this country is still poor. And I only get one choice: Spectrum. Unless I quit my job (won’t happen) and move just for a different ISP, I’m stuck with crappy internet that struggles with streaming.

I bought La La Land which is supposed to 4K but it doesn’t seem to play in 4K on my 2017 iMac 5K. Downloaded the movie gives me 1080p HD. Streaming it seems to look a bit better but doesn’t look 4K to me.

on iPad Pro and iPhone shows I can play it in HDR but that’s not the same as 4K.

Seems odd that 5K iMac cannot play 4K movies.
