So while testing what you asked for (which was no problem, the conversion is great (goes to 352.8kHz which is great to see it's trying to output the best it can, instead of doing something like 48, or 88,2kHz).
Okay, so now we have something interesting... For some reason, the error message about LG phones on Android 10 not working in terms of outputting DSD over DoP is gone. What's more, it's actually piping out to my DAC. What the heck is going on lol...
Works for both DSD64 and DSD256 (RME doesn't support 512 I think, nor do I have any 512 albums).
Also this isn't mis-reporting, the RME is actually playing back and reporting both DSD64 and DSD256 properly.
Now I don't get what the heck is going on anymore..
