It does use the same technology as dnf, but doesn't use dnf directly,
it is PackageKit based,  maybe you can get some information from
'pkcon' which is PackageKit's command line client, also could be that
there is another way to get the history of PackageKit transactions, but
I don't know, I mostly manually use yum/dnf.

They "do use" the same repos, but don't share repo metadata/cache
currently, so they can "hit" different mirrors and have different data

I'm not sure how it works, it could be that it considers metadata/cache
valid so it says it is up-to-date or shows last state when it did check
for updates, until you force it to re-check which maybe re-downloads
metadata/cache
