I was that way. I have a home theater, and can view and listen to every format of audio and video. Netflix used to have 3D movies, which I am addicted to (Not really, just like 3D movies.....can't wait for Avatar II to be released!) Netflix, and Amazon are pretty poor sound wise, 5.2 Dolby D, and that's about it. Someone said try Vudu, their movies, if available with all the sound and vid options are great, as long as you have high speed. I do. I noticed on Vudu, Top Gun Maverick was offered in UXD video and ATMOS sound, so I said, what the hey, and bought it. It was perfect! Only thing missing were the EXTRAS found on the disk but that's ok, the 4k UHD DVD is coming.
VUDU has made a streaming denier, opportunist out of me.
Going to be interested in Avatar II, I wonder if they will offer it in full 3D and ATMOS sound...Bet they will.
Seriously, if you have the equipment, give them a try. I don't think you will be disappointed.
