In terms of defining what the output means, is there really a
difference between these two?

The Solaris one does a modest check to see if the name is unused.  But
since it doesn't hold onto that newly-created object, anyone else
could slip in a millisecond after mktemp(1) exit and create that same
object with nary a complaint observed.

I don't see now it's an architectural distinction.
