It also lacks Dolby Vision and Dolby Atmos support, but it still supports HDR10, HDR10 Plus, and Alexa Plus while including an Alexa Voice Remote. You also get access to all the major streaming services, while Xbox Game Pass Ultimate subscribers can stream select games from the cloud as they can on Amazon’s other sticks.
