Dolby Atmos' particularity is that this is the object-oriented sound format, that is, each audio signal object is independently sounded and connected to its spatial position. Denon AVRX4400H can create 3D sound due to the Dolby Atmos support.
DTS:X is an algorithm used by the processor to create sound scenes, where sounds connected directly to objects rather than channels, and to determine the optimum sound output distribution in space. Surround sound with DTS:X is available only on the AVRX4400H.
Auro 3D gives a bit more versatility than Dolby Atmos or DTS:X and provides a hemispherical sound and enables a receiver to produce 3D sound stages. Only the Denon AVRX4400H has Auro-3D on its feature list.
