I encountered the same issue on my Roku Premiere - 3920X running 12.5.0 build 4178-91
My Roku account shows I’ve uploaded pictures (which I did from my phone). it also shows the the Google Album linked to the stream. I’ve tried to add remove the Google Album, but it doesn’t seem to make a difference. I just the see the two stock photos on the screensaver.
I don't know if this will help, as I've done all my Photo Streams uploading and stream creation via the website on a desktop computer, not via my phone. I've created several different streams, some of them seasonal, and can choose which to include in the screensaver at any one time.
At https://photostreams.roku.com/streams below each stream I have created there is an "include in Roku screensaver" checkbox.
