Netflix & Amazon use Dolby Digital+ with Atmos layer. True Atmos is recreated via 5.1 or 7.1 and I think 32 channels in a Cinema creating up 128 objects in the mix. With 4k UHD Discs it used with Dolby True HD as the Base layer with Dolby Audio Codecs and Advanced Scaled Algorithms to create that 3D Object based Immersion.None of the streaming services Netflix or Amazon Prime stream in lossless atmos just lossy atmos so eARK doesn't matter even the apps on your UHD player your still getting lossy atmos.
