Thanks for the details and it is really helpful. I completely get it. I have a 5.2.1 system in my living room with a fire tv 4K connected to an Anthem MRX720 but doesn’t output Atmos. I can get Atmos from my Nvidia Shield tv pro with the same Netflix and Apple TV shows. So Nvidia recently started supporting Apple TV. Also in the bedroom I have an Atmos sound bar Sony Hts 5000 and the fire tv is connected to my tv with the arc connected to the soundbar from the tv but still no Atmos. So I was wondering if the fire tv 4K outputs Atmos at all and if the newer one would work better.
