Just tested it on my Apple TV 4K (older addition). Already works with apps. Even Netflix!!!!
Sounds amazing on my AirPods Max. Now I no longer have to use my iPad as my streaming device to get spacial audio. Made my day.
How did you get your tv to update? I can't seem to find an update after adding the profile

EDIT: Figured it out. Turn off get beta updates and it shows up.
 
Hope they add IR learning for the Power button on the new Siri remote in tvOS 15.

For all owners of Apple TV with TVs, Projectors, AV Receivers and Soundbars without HDMI-CEC or incompatible HDMI-CEC, they need the new Power button to send IR for On and Off and IR for switching HDMI input to Apple TV.

Shouldn't be that hard for Apple to add learning IR for the Power button they are already doing the IR Learning for Volume + - button and Mute button. Settings App > Remotes and Devices > Volume Control. Select Learn New Device…

I realize that learning IR for Power On/Off requires you to cover up your TV/Projector IR sensor or have the Apple TV positioned so it can learn the IR for Power On and Off without the TV/Projector receiving the IR and turning off in the middle of learning.

To avoid the problem of a TV or projector turning off during Apple TV learning the Power On Off IR codes, Apple could do it with the help of an iPhone like they now do for Color Calibration since tvOS 14.5. Settings > Video and Audio > Calibration > Color Balance.

The new Power button should be able to control both a TV (or Projector) and Soundbar (or AV Receiver) via IR and switch the HDMI input to Apple TV. Some devices require discrete Power On IR and discrete Power Off IR, instead of Toggle Power On/Off IR. Apple needs to support Learning both types. (for example, to turn off many projectors you need to send discrete Power Off or send Toggle Power On/Off IR twice).

Apple advertises IR support for Power On/Off:

On the Apple TV 4K Tech Specs page it states “Control your TV or receiver via IR or CEC”. With footnote (3): "Powering on and off, switching input to Apple TV, controlling volume, and mute.

There are other ways to solve the issue if you don't get the button you want.
My new TV has HomeKit in it, so I program various Automations (like leaving the house, and the button I press when I go to sleep to switch off all the lights) to power it down.

But for my old TV I used a smart socket to do the same thing. If you want a control in the TV room there are various options, from HomeKit control on your Watch (I have two Shortcuts on my Watch as complications) to HomeKit control on your phone to speaking to a smart speaker (could even be Alexa or Google if you get the appropriate smart socket) to getting a smart button.
Some smart buttons are still expensive, but Ikea has one that's pretty cheap -- and Ikea also sell smart sockets that come with a pre-linked on/off button that you can stick to the wall, or your chair, or wherever. Or you can go non-smart and just get a radio-controlled socket with associated on/off controller; those are very cheap these days.
 
It works.

So to try being precise is the following correct?

TODAY (ie tvOS14)
- Atmos-encoded content sent to your TV will be handled by the TV. Meaning if you have a surround system of some sort, the TV and/or surround system processor will mix the Atmos down to your 7.1.4 or 5.1 or 3.1 or whatever speakers you have, and you will get surround sound from your soundbar+whatever extra speakers
+ the Apple TV has nothing to do with this except passing through the Atmos signal to the TV/soundbar proper
+ the angular behavior (as I turn the sound turns) happens because the speakers stay still but my head turns

- Alternatively I can tell aTV to send audio to a HomePod or two. In this case the aTV does decode the Atmos, generates an appropriate spatial signal for the HomePods, and, like above, I hear spatial sound as I turn my head.
(Presumably the multiple speakers on a single HomePod allow for some sort of spatialization beyond just stereo separation?)

+ if I tell aTV to route audio to AirPods rather than HomePod, now I just get a stereo signal from aTV, all the additional spatialization content is tossed.


TOMORROW (ie tvOS15)
- signal sent to the TV is unchanged
- signal sent to HomePod(s) is unchanged (except HomePod mini now also gets to play)
- signal sent to AirPods is modified based on my head orientation. Unlike the speaker case, when I move my head, the airpods move as well. So the aTV needs additional feedback (presumably from gyros in the airpods) that I have turned 30 degrees, and it modifies the signal to match that new orientation.
Presumably, also,
+ when this starts, the system has to assume you are facing the TV, and all changes are relative to that? If you put the airpods in with your back to the TV, then start turning, by the time you're facing the TV left audio will be on your right and vice versa?
+ do the airpods gyros also track vertical angle? ie if I bend my head to look at the roof, do the airpods know I have done that? Unclear to me. The final 4 in 7.1.4 means (in theory) that your sound system is also generating "vertically differentiated" sound, not just sound from different angles in the plane. But I don't know if (current) AirPods can provide that.
+ I'm assuming the airpods track ONLY angle, not position? But this is unclear to me.
Suppose I'm in a room listening to my fancy surround-me orchestra. I rotate and hear the violins are now coming from behind, no longer my left. OK, great. I'd also expect maybe that if I walk towards the violins they get louder.
BUT supposed I am now out walking in the street listening to the same content. What do I want? I certainly don't want violin loudness tracking my movement in space! Maybe I want them tracking my head angle? But even that becomes problematic when I hit a corner and start walking north-south rather than east-west...
(This last is no longer an aTV question, now it's an Apple Music and Spatial Audio question!)

THANK YOU!!!! Be struggling with this since yesterday o_O

Do you need audioOS 15 in order to get HomePod minis to connect to tvOS 15 as Default Audio Output? Default still shows as TV Speakers with tvOS 15 and the HomePod mini stereo pair still show under Temporary Audio Output.
 
I just installed a Homepod Mini and it did an upgrade. I also just installed TVOS 15 public beta to my ATV. I noticed later my Siri remote was having a connection lost/reconnect chase till it finally lost connection. Anybody else notice this? I haven't had the remote that long and I was not able to see the charge state but I did fully charge it to start with.
