 In LOTR there are no cases of Gandalf 
not seeing the wearer of the One. 
In "the Hobbit"  the evidence is controversial IIRC: maybe he did, maybe he did not. 
Note also that at the time of writing of "the Hobbit", Tolkien has not yet developed the conception of the Spirit /Shadow World versus the World of Light, had no idea about the nature of Bilbo's Ring and had Gandalf as a Man, not a Maia. "The Hobbit" is not a good source of evidence for such things.
