Dolby Atmos support has been on the block since the debut of the Xbox One in 2017, so it's no surprise that it was a success on Xbox Series X and Series S. That said, a license is needed to use the spatial audio tech on headphones, but it's free to use on soundbars and speakers.
Dolby Vision gaming requires a compatible display but is also accessible to those who can enable it. Currently, however, not every TV that supports Dolby Vision gaming can output at 120Hz, but Microsoft and Dolby are working closely with TV manufacturers to update more displays.
