This is why I got a Roku instead. Fire TV does not allow access to Vudu. As far as streaming services goes, VUDU is the only provider that manages near bluray quality in both video and audio. Not only do they provide atmos on their UHD titles where atmos would regularly be found on the bluray, but they’ve recently dropped the price on them to where they are often cheaper than Blu-ray.
I really don’t understand why Netflix can’t provide atmos on other devices. Atmos is nothing more than metadata attached to the DD+ stream that instructs the avr on how to process the audio as objects vs channels. Netflix already utilizes DD+ on their titles, and metadata support has nothing to do with the platform or device.
