I bought the CEE 3D BD of Zootopia from eBay. It has a russian audio track in Dolby Digital but the ukrainian is DTS-MA.

Im aiming for always the best quality but a higher quaility track is nowhere avaiable, the 2D disc has the same audio. And no UHD version for Russia...

On some 'not so white' sites, there were remuxes of other movies where an custom Atmos track was mixed from the english source and rus AC3.

Is there some guide or any info i could look into somehow?
