There's Dolby Atmos for Mobile Devices[0]. It does require extra processing, so maybe extra hardware, but it's not unique to Apple.

I would think Apple TV + hdmi should do the trick. There doesn’t seem to be a technical reason this can’t be done seeing as atmos does work on Apple TV, but.... I would rather have my TV off when just having music on.
