Get this:

On PC:
There is no Disney+ app for Windows, so you have to use a browser.
Max resolution is 720p no HDR
2.0ch stereo

On Android smart TV:
Max resolution is 4K with HDR
But 2.0ch stereo

On PS4 Pro:
Max resolution 1080p (I think) no HDR
With 5.1ch surround

Please tell me there is a way to watch content on the service where I can get the maximum available experience on my TV without having to spend hundreds of dollars on a device that has an app which allows it.
