Just got an Arc Ultra and have it with a TCL R646. I can't get Dolby Atmos to work (the tv does support it). I've tried all the settings on the tv but the best I can get is Dolby Digital Plus 5.1. I've tried Netflix, Disney, Prime and Paramount+.
Any ideas?

Hi
Welcome to the Sonos Community!
Sorry to hear of this issue you are having with playing Atmos content on your new Arc Ultra.
Also just tried a movie on my ps5 with Disney+ and it shows it playing Dolby Atmos.
As you are able to play Atmos, everything to do with your TV and your Arc Ultra is set up correctly - when you don’t get Atmos, that is now presumably due to the TV app used (and possibly it’s settings), the content, or your subscription level.
I hope this helps concentrate your efforts to the right location.
Are you using the TV’s native apps? Do you have a Netflix Premium subscription and the “ad-free” Prime Video subscription?
Dolby Atmos is only available on Netflix with a Premium subscription.
Try testing the film The Tomorrow War on Prime Video.
Also be sure to set the Digital Audio Out setting on the TV to Pass Through.
I just tried The Tomorrow War and the Sonos app is saying it was playing Dolby Digital Plus plus 5.1
I checked and it is on pass through as well.

Are you 100% sure you have the “ad-free” Prime subscription? If so, Dolby Atmos may not be supported on the TV’s native Prime Video app.
Now that you mention it I don't pay for the upgraded ad-free version.
Paramount+ I have a premium account and it plays in Dolby Digital 5.1 when the movie descriptions says it has Dolby Atmos.
According to Paramount+, it should work:
If you have the Paramount+ with SHOWTIME plan, you can stream movies with Dolby Atmos, which is a popular surround sound format! Currently, Dolby Atmos streaming is available on these devices:
