Dolby Atmos and DTS-HD 7.1

[JB122]

My setup is Denon AVR-770H, 7.1 speakers, Sony OLED TV, Apple TV 4K. I am using Infuse Pro 8.2 to view videos from my server. My problem is the Denon Receiver does not indicate that Dolby Atmos or DTS-HD is being played. If I play a physical disc, or an iTunes video through the Apple TV, the audio type is clearly displayed on the Denon Receiver. Playing MKV files through the setup results in Multi Channel stereo being displayed on the receiver. What am I doing wrong? The MKV files indicate that Dolby Atmos is present and it is selected via the pull down menu when playing.

It seems like it is working as it should.

Thank you, that does clear up my confusion.
