Third party ATV apps Atmos for Homepod

Since the introduction of 14.2 the Dolby Atmos offering of Netflix, Apple TV+ and Itunes has been great, but what if anything is being done by third party apps to meet this requirement (over Airplay) ? I am specifically talking Amazon Prime Video, Disney+ and Tidal (Atmos Music). With a significant price hike coming from Disney+ i would hope that they find a solution.

If anyone has any inside info on how these ATV apps are being developed to offer Atmos to Homepod, i would be interested. I know its "pseudo" Atmos, but it sounds better than 5.1....
