Thank you much sir. Are there certain streaming boxes that can play these files back using Plex? I currently have an Apple tv4k. I’m assuming they download in mp4 format.

StreamFab can download in MP4 or MKV, there is a setting for this. I believe the default is MP4 (but its been a while since I did a fresh install, so I don't remember).
My basement (with 5.1.4 with ATMOS setup) is a couple of weeks away from being finished.
Long story short, since my family room setup is only 5.1 speakers, I can't enable ATMOS on the receiver to know if it will indicate ATMOS when playing. That being said, the input info the receiver shows for these files while playing is exactly the same as playing them back from Amazon, HBOMax or Disney+ so they should give me ATMOS when played locally. With Plex and my Roku Ultra 4800 and Roku Ultra 4760, there is no audio transcoding happening for these files.
I don't have an Apple TV device. So I can't say how that handles these files.
So as long as your setup supports ATMOS (i.e. your sound bar or receiver/speaker setup) then you should get ATMOS playing these back.
