If you have a fancy 4K TV and a decent sound system with Atmos which you want to take advantage of then you really should be buying physical media instead of streaming... I mean, if you went beyond having a sound bar, and ran wires for surround speakers with a proper home theater amplifier.
Streaming platform usually only give you 5.1 on EAC3 (DD+), on UHD Blu-rays you get 7.1 over TrueHD, and then you get Atmos on top of both of those, and Atmos over TrueHD is more Atmosy or something (besides obviously TrueHD being lossless while EAC3 is lossy.)
