I’ve seen both versions around. On iSeries DB2 you can use either and as far as I can tell they do the same thing. Is there a difference?

No, there is no difference because DISTINCT is a keyword and not a function call.
It’s the same difference as between
SOME_COLUMNand(SOME_COLUMN)(without any keyword in front)
