A detailed update to my issues, in case anyone is still able to help. I've since found the issue is not specific to 7.1 audio, it's related to newer, higher definition audio formats. And also, though I do have a Roku Ultra, it's actually a 2018 unit, so it's likely different than the specs I posted above which are from the most recent model.
My receiver shows the audio input signal as well as what it's outputting, so I've been using that for troubleshooting. The input to the receiver has been particularly helpful, as it is my best indication of what's coming from upstream (i.e., Jellyfin/Roku).
I've clarified the issue that I've been having is that any Dolby TrueHD / Dolby Atmos audio content was coming in to my receiver as PCM 2.0 input, and therefore only achieving 2 channels of output. The same is actually true of some other higher resolution audio formats as well.
I've set the Jellyfin client on the Roku to prefer the DD (AC3) audio codec. Now all of my media is at least coming through to my receiver in Dolby Digital 5.1 channels and I'm getting proper outputs to the 5.1 speakers. This is an improvement.
The Jellyfin client in Roku also offers AAC, DD+ (EAC3), and DTS preferred audio codecs. When I sent to any of the other three, my receiver sees only PCM 2.0 input for the True HD / Atmos content.
So here are the current Jellyfin formats and how they are showing up to my receiver. You can see there is even some inconsistency.
My suspicion is that the Roku and the Jellyfin client are what are holding me back. I know the receiver can and has seen a wider variety of format inputs; even my old Blu Ray player delivers a wider variety of audio signals from various discs.
Any additional input appreciated. Thanks!

- Dolby TrueHD + Dolby Atmos > DD (Ant Man and Wasp 4K UHD)
