 TV+ app says “spectacular 3D” using Vision Pro

I subscribe to several streaming sources. Some are direct to company, some are thru my cable provider and one is thru the Apple App Store. When I am using Vision Pro and search for 3D movies, I get a list. Many, perhaps all, are supposedly available on streaming services. I select a streaming service I subscribe to, but only get 2D video. There is no choice for 3D, even though Apple thinks there is. I get other options, such as rent/buy from Apple, or start a trial subscription to a service I already subscribe to. Am I just confused? Can anyone help? Do I have to rent/buy from Apple to get 3D after paying them $4,000?
