There are only 3 ways to get true Atmos on headphones.
1. Smyth Realiser A16 - Accepts a TrueHD, E-AC-3, or MAT 2.0 Atmos bitstream over HDMI from any source.
2. Xbox - UWP applications such as Netflix can play Atmos content with object-based rendering when used with the Dolby Atmos for Headphones spatial sound renderer. If you use any other renderer it will play only the 7.1-channel base layer. Games support object-based rendering with any renderer.
3. Windows 10 - Same as Xbox. Additionally, E-AC-3 Atmos media files played in the Films & TV application or Edge browser support object-based rendering. Non-Media Foundation applications will play only the 7.1-channel base layer even when using the Dolby Atmos for Headphones renderer.
The ideal setup is a Windows 10 PC bitstreaming Atmos to a Smyth Realiser A16. Then you can use any application.
I don't know why AVRs don't have a Dolby Atmos for Headphones downmixer.
