Although we have had issues with AppleTV and Atmos, thru a DM16x16 with 4KZ in/out/rmcs... They are specified to be compatible with the Dolby and DTS immersive audio formats.
The DM and NVX (and other devices like AVpro) aren't designed to 'decode' these formats, just pass them thru to the devices that can, unless I'm missing something in your comments...
My basic beef with modern high-res AV formats is that when they work, they are magical...but they don't always work (usually at the most inopportune times...)
Unfortunately, until we as an industry tell the developers to make existing things reliable before coming up with some new/better? thing, we will continue to have pain.
I for one hate having to tell our clients the truth...
"Sir, would you like reliability or the latest formats??..."
Sadly, I've found that setting up a high-end system at 1080p with 2ch audio and a SSP set to decode to an approximated immersive sound field is the only way to not get angry 'no picture or no sound' call backs.
Like selling a Ferrari to only drive 30 MPH on small town roads...
