On my LG OLED, the Disney+ app delivers UHD and DV, but also 2 channel PCM audio.
On my bedroom Sony 900e with the Disney+ app, I get UHD with HDR10, and DD+ audio over ARC to a Marantz 1608, just as I do with Netflix.

I just found this group, and without reading almost 2000 posts, can someone please tell me if the Amazon 4K stick delivers full DolbyVision/HDR at UHD resolution and up to Dolby Atmos (when available) audio for Disney+, Netflix, and Prime?
The Amazon page selling the thing says it does, but I'd like to hear from an actual user that it's true. I asked the question on Amazon, and got several uninformed replies (like "The 2nd gen Fire doesn't support UHD" - it does).
So far, from what I've read, only the Apple TV 4K will deliver everything video (UHD plus DV/HDR) and full spectrum audio with Disney+ and other streaming services/apps.
What tv do you have? I have an E6 OLED. If I manually force the Fire TV (in my case the Cube 2) to 2160p, I will get 4K HDR10, but not DV with Disney, because my TV does not support 4K60 DV. If I set resolution to Auto, with frame matching on, everything from Disney is at 1080p including HDR10 and DV. I don't believe Disney works properly with frame matching and Auto resolution if the tv can't support [email protected]
, and thus will downgrade everything to 1080p. In fact, the Netflix app does the same thing. If I want 4K from the Disney or Netflix app, I have to manually set the Fire Cube to 2160p, but then I only get HDR10. Until those apps sign on to allow frame matching through the Fire device, I won't get 4K DV. Amazon prime video on the other hand, when I set resolution to auto, and frame matching to on, I get 4K DV @24hz.
With that being said, I can not tell the difference in PQ between 1080P DV via the Disney and Netflix apps on the Fire Cube, and the 4K DV stream via the tv's internal apps. They both look exactly the same.
