Amazon Prime & 7.1 or Atmos Decoding

So after trying both the 4K Firestick and the 4K Cube neither product will broadcast 7.1 on Netflix or Prime. In fact I could not find one single movie or series in 4K that use Atmos
This is even though both products state they do in the Amazon advertisement.

So, I sent back the Amazon 4K Firestick and cube and bought the Apple 4K TV device.
I have noticed that there are now a few titles showing up as 7.1 or Atmos on my TV screen information.

But, I have yet to hear a sound out of the rear speakers in a 7.1 set up through Netflix or Amazon Prime. Again, 4K disc’s and Blue rays play 7.1 fine.

Why is it that I cannot get the 7.1 to play through my Oppo 205 HDMI input? I even contacted Oppo who surprisingly wasn’t much help. They must have given up on consumer audio/video.

So, I discovered this info on page 82 of the Oppo 205 manual in regards to HDMI input.

HDMI Audio: up to 7.1ch/192kHz PCM, up to 5.1ch DSD, Bitstream. 

So does that mean while using a 4K Apple TV or a 4K Firestick device connected to the Oppo 205 via the HDMI input, it will not input 7.1 into the Oppo 205 just 5.1? 

It sure seems that way.
