All Roku players except the base Express support 4K. All Roku players support 5.1 Dolby Digital, but they must be connected to an audio device that supports DD. Atmos is supported in the Ultra, Express 4K+, and I believe the Streaming Stick 4K. But again you must be connected to an audio device (usually an AVR or soundbar) that supports Atmos.
However, Atmos availability on streaming services is hit or miss. I don't know anything about Hulu, as I don't use it. Prime Video has very little content with Atmos. MAX requires a subscription to the highest tier for 4K and Atmos. Disney+ seems to have a fair amount of content with 4K/Atmos.
That's helpful. Thanks. It's still so general though.
I guess I will need to research more about the statistics of app-specific 3+ audio channel content.
I'm thinking asking here via roku won't get real answers and I might get better details asking at a place like amazon prime video tech support forum since it reduces the number of variables, unless someone chimes in saying that they already research this question and got the real answers. (But to be clear that's only one app of dozens I use.)
You asked a general question, so I provided a general response. I can't be specific about Hulu since I don't use it. But I did provide more detail specific with Prime Video, MAX and Disney+. If you ask something more specific we can likely provide you with a more specific answer.
Asking about Hulu on a Prime Video support site will get you nothing. Hulu is owned by Disney, not Amazon.
That image you posted shows an example of a Prime Video title. Notice it doesn't say anything about Atmos, so it's highly unlikely that title has it. On Prime, the vast majority of titles with Atmos are Amazon Original titles. I have a number of movies that I have purchased with digital copies. Many of these are UHD titles with Atmos audio on the Blu Ray discs. I can access those digital copies on Prime Video, along with Vudu (now Fandango), Google Movies, Apple TV and Movies Anywhere. But when I look on Prime Video, even if the title is available in UHD (not all are) none have Atmos. But if I use the Movies Anywhere app I can get Atmos audio. So don't count on Prime Video to offer much of anything with Atmos.
I actually upgraded to Dolby Atmos just to get surround sound once Roku programmed obsoleted their older models. (They disabled TOSLINK.)
"Atmos availability on streaming services is hit or miss"
This might be the most important sentence you wrote, Dan. I'm wondering if the best place to ask the question might be avforums then. It looks like because Roku now requires Atmos to get surround sound content, and most content is not actually encoded in Dolby Atmos, that Rokus, statistically speaking, are not the best streaming solution as compared to Amazon Firesticks, for example.
