Hopefully this is a simple question. I'm curious whether the core audio tracks for Dolby Atmos and DTS-HD Master Audio are the same as the secondary audio tracks often found on the disc.
For example, on Zack Snyder's Justice League, they offer Dolby ATMOS and a 5.1 Dolby Digital track. Would the core track for the ATMOS be the same as the 5.1 Dolby Digital track they included?
I have the same question concerning DTS-HD Master Audio. Often discs will have 7.1 DTS-HD Master Audio with a 5.1 DTS core, and also include a secondary track that is 5.1 DTS. Would these two 5.1 DTS tracks be the same?
I'm just curious if these are indeed identical tracks, or if the core is mixed slightly differently than the separate track.
