I haven't really heard any Disney lite discs per se as I'd have to buy a 4K disc on top of the 3D one I normally get. I do have the Ralph Breaks the Internet combo coming from Japan that has both, though. But I imagine they're similar to the current DTS:X discs in nature. I get around all that with extraction and matrixed speakers beyond 7.1.4 so it doesn't impact me the same way it does a Denon 8500 or Trinnov owner. (DTS:X Pro may change all that as Neural X can do internally what I'm doing externally once the 11-channel limit is removed. However, Atmos will still be affected by those Disney titles as they do not allow third party competing upmixers to be used with Atmos (and seem to want to stop Neural X from even being used with the base 5.1 or 7.1 track).
The real concern, IMO, is that larger home theaters that really need more than 11-channels for even coverage (phantom imaging falls apart after a certain angular distance) won't sound right. It's why I have the external solution instead of an 8500 as my top middle speakers work with everything (including Auro-3D).
