Both audio & video qualities on those streaming movie services (Netflix, Amazon Prime, Apple TV, Hulu, Vudu) are compromised and cannot compare to that of bluray & 4K UHD bluray discs.
The only thing that is of equal qualities (audio & video) or possibly better depending on what kind of bluray/4K UHD bluray players you have will be the Kaleidescape Strato 4K movie server/player that allows you to download 4K UHD, bluray & DVD quality movies. But this is not streaming. It is a movie server / player and you can only purchase the downloaded movies (4K, bluray & DVD) from their own online store only. The Kaleidescape Strato 4K movie server/player are expensive but can store hundreds of movies of varying qualities (4K, bluray & DVD). You can also add their Terra movie server to your existing Strato and the Terra movie server can store up to 40TB and can be linked to multiple Strato movie servers.
The audio qualities of these Kaleidescape Strato 4K movie servers/players are bit to bit perfect to studio mastering qualities and are formatted in either Dolby Atmos, DTS-X, DTS-HD Master Audio or Dolby True HD on the bluray & 4K UHD quality movies and Dolby Digital & DTS on DVD quality movies. Video qualities are top notch as well. They use very advanced video processor. One reviewer from I believed Hometheaterreview.com did AB comparison to his Oppo UDP-203/205 player using HDMI to his AV processor and he said the picture and sound qualities of the Kaleidescape Strato 4K movie server/player is identical to that of his Oppo UDP-203/205 player for 4K UHD & bluray disc playbacks.
But again the Kaleidescape Strato 4K movie server is not streaming. It is a sophisticated advanced downloaded movie server / player. Kaleidescape collaborates together with major Hollywood studios and the newly released Hollywood features will be made available in Kaleidescape Strato before they become available in bluray/4K UHD/DVD discs. But they are expensive and you are limited to only major Hollywood studios movies. You don't have access to independent and foreign movies.
