I can't find any evidence that Overwatch supports anything other than Atmos for headphones. Even Dolby's page
only mentions headphones for Overwatch while it mentions speakers or headphones
for Gears of War 4. Modern games are very specific, if a headphone output method is advertised, that usually means that the game itself supports that one specific feature. If Overwatch specifies 'Atmos headphones', that means the game's audio middleware (Wwise), completely independent of any other software installed in Windows, is outputting a stereo signal with Atmos surround virtualization, just like games that support HRTF. If you're using the Atmos app in Windows and you're getting audio in all speakers from Overwatch, the Windows app is probably up-mixing the audio output from the game, that's similar to how every 2-speaker 7.1 headphone works; additional software running in Windows mixes the audio output from the game to be output through stereo headphones. In this case, the Atmos app would be upmixing stereo Atmos output from Overwatch. I'm getting the impression that the Dolby Atmos app just upmixes; why would you need an app to use a feature that should be properly detectable and usable through an HDMI interface?
It looks like Battlefront and Battlefield 1 properly support Atmos for home theater speakers without the need of additional software
To experience Star Wars Battlefront in Dolby Atmos on PC, you'll need an NVIDIA® or AMD® graphics card with HDMI® output and up-to-date PC drivers.
No mention of the Atmos app there, it sounds like it's supposed to just work provided you have a recent GPU connected via HDMI to an Atmos receiver
At this point, I think that the Windows 10 Atmos app is useless if you're expecting to get discrete Atmos output from games; what is its purpose other than to upmix? It appears that if games or media properly support Atmos for home theater, they'll determine that functionality themselves via the HDMI connection between the output device (Xbox, PlayStation, PC) and the AVR and then directly use the Atmos feature of the AVR; no Windows app necessary.
