You get all of them, since they tend to be ripped as-is from the source media. I commonly see Dolby Digital+ (because Netflix/Prime/etc. use them), Dolby TrueHD (because BluRays use that) and nowadays there's more and more Atmos. Ocassionaly you can see an odd DTS/DTS-MA now and then, but not a lot.
