I think, Sauron would be threatened by anyone who was able to master The Ring, unless Sauron believed it was totally impossible. I don't think Gandalf and Galadriel were deceived by The Ring to the extant they were incapable of estimating their own potential.

Sauron wouldn't be threatened by the wearer of the ring at all. Look what it did to Gollum, Bilbo, and Frodo. He created the ring to be debilitating to the wearer, and knew that the ring would make them succumb to his darkness.

And yes, I believe you are right about Gandalf and Galadriel, as they were both put in the path of temptation and both rejected it.
