Doesn't basically every Hollywood movie since DVD pay a licensing fee to Dolby (or DTS) for 5.1 or Atmos (or DTS:X) support? Theaters too even? And wasn't Dolby B NR insanely widespread on pre-recorded cassettes? Like so common that most albums on cassette from the 80s have the Dolby logo on them? I don't think its that weird. It's clearly been done in the past. Apple's limitations on what devices works sucks and it'd be nice if we could buy these tracks DRM free to play on an Atmos speaker setup but they aren't the only ones to have this. Tidal has Spatial Audio, Amazon does too. Each does it a little differently as to what is supported annoyingly but hopefully as time goes on those limitations will go away.
