This was collected via snapcraft status communitheme (as part of snap author creds). I don't know of any snap command giving you this info.

Note that snapcraft doesn't deduplicate between arch: amd64 and arch: all (because we switched recently to arch: all).
However, there isn't repetition of edge/communitheme-snap-helpers-pr4 contrary to the screenshot.
