As written in the spell description of dispel magic, a 3rd level dispel magic also can dispel a 9th level spell with only a check, that didn't stop them from writing some things that explicitly stated that dispel only works for that effect if cast at 9th level.
I've never seen it on a magic item so far, though I've often seen items or monster effects describe it can't be dispelled with anything short of Wish, maybe that's the one?
