Will Apple ever offer Dolby True HD for iTunes films and Apple TV 4K?

Backbone support for DD+7.1 seems to be here already: Dolby Audio support in HTTP Live Streaming

That is definitely the case, given that some movies from the iTunes store have 7.1 tracks.

Thing is, I don’t know if non-UHD movies are really streamed using HLS. They can be downloaded iniTunes, so aTV could also just download them as a file. The pre-buffering also supports this idea.
I would not be surprised if streaming-only UHD content is actually served using different technology.

Well, you can easily test this by playing a 4K movie with a 7.1 track (e.g. Deadpool, The Revenant or The Martian).

Good hints! I will take a look at them.

DVD audio does not carry any metadata, as far as I know. It is just a plain stream of compressed audio signals.
Apple currently seems to max out at 30Mbps when streaming it's 4K movies and that is consumed mostly by video data.
Take a look at this screenshot: #65
You will see, that video bitrate is north of 28Mbps, audio bitrate is only 384kbps, which is common for heavily compressed dolby digital (next common values are 448 and DD5.1 maxes out at 640 kbps).

But look at studio recordings... You won't get 48K sampling on a CD, because there isn't enough room, even if you try and compress it and can get audio equipment with decompression in. It just won't be as efficient..

You can get great audio/video, but how quick it decompresses would be all important i would think.. The more you have, the slower it will be if it can't keep up with the hardware.
