- Amazon HD is an automatic service containing all the releases delivered to Amazon that fall under their definition of "HD" (high quality / 16 bits).
- Amazon Ultra HD is an automatic service containing all the releases delivered to Amazon that fall under their definition of "UHD" (ultra high quality / 24 bits)
