Both audio settings are Auto Dolby. The Atmos test files will not play in Atmos. What follows is an "enlightened" conversation with Roku Tech Support.

(06:12:07 PM) John: I attempted to play a Dolby Atmos title "Lucy" from Vudu. The Vudu info playback screen stated Atmos. however the processor only indicated Dolby Digital+ as the audio source. I have set the Roku for Auto Dolby Digital, DTS in the setup menu. Is this a known issue?

(06:50:17 PM) Jaime: Hi there thank you for contacting Roku support.
(06:50:35 PM) John: OK!
(06:51:33 PM) Jaime: May I ask for the serial number of your Roku device?
(06:52:21 PM) John: It is in the equipment room about 50' away. It is a registered unit.
(06:54:19 PM) Jaime: Does the movie wont play?
(06:54:52 PM) John: No, the movie plays in 4k but without the Atmos data.
(06:55:26 PM) Jaime: I see, what is your Roku device?
(06:55:35 PM) John: Ultra
(06:55:51 PM) Jaime: And the resolution of your TV?
(06:56:08 PM) John: Full 4k 60
(06:57:58 PM) Jaime: I see, so without the Atmos data it wont play 4k?
(06:58:21 PM) John: Jamie..I am out of time. I must go!
