Let me say up front that I don't use Roon so my answer is not 100% relevant to you but I'll share what I know about streaming wirelessly to my 205.
After seeing a thread on here titled "Oppo 205 + Tidal/Roon Via Ethernet Now - Should I add a MQA decoder? - need your wisdom" and following a couple of the links from thread contributors, I discovered how to stream wirelessly to my Oppo 205 to get MQA unfold on Tidal. I loaded the mconnect app onto my iphone and use it to select Tidal (it supports Qobuz as well) and then select the Oppo under the 'Play to' option.
I can use either the dac in the Oppo or use the digital out from the Oppo to go into a psaudio dac. The mconnect app seems to allow for getting files from cloud sources or local servers also but I can't comment on this as I've not tried to use these options.
This is a relatively recent development for me so I haven't yet done head to head comparisons between the wireless streaming and my original streaming method, laptop to spdif optical to the psaudio dac. I don't know if this helps you at all but my main point is to be aware of the mconnect app and see if this is a path that might work for you. Best of luck!
