would an istari or a bearer of the 3 be able to see frodo if he wore the one ring?

I have always wondered this, as we know the nazgul could see frodo when he put the ring on down to fact they have faded into the shadow world. But we also know that the istari and the bearers of the 3 or any elves that have seen the light of the two trees could see the nazguls true form, so my question is would an istari, high elf or bearer of the 3 be able to see frodo if he wore the one ring?
