Looks about the same. Would just keep it in qt for a while. Don't look infected. If it's something that's infectious then it'll manifest eventually. Either get worse or the fish will die.
It got some meds I wouldn't give any more abx. Just wait it out. I think by keep it in qt and time it'll clear up.
Its not looking worse so that is a good thing. I would give a little more time to heal away from the other polys. That way there is no chance making it worse with feeding competition where it could accidentally get injured with a misplaced bite.
