Why doesn't Disney do Dolby Atmos for their blu rays and only the 4k UHD discs? They still only have a DTS Master Audio option. Fox is the same way. Now it's great for the UHD 4K, but if a film was done in Dolby Atmos, both the UHD 4K blu ray and regular blu ray should be in Atmos (yes I know it's True HD for the home). Warners does it, so does Lionsgate, and even Universal.
