I agree that the dealer could have changed the tires/gears (or anyone else could have...), but I doubt that they would have changed the door tag to indicate this.

So the only way to know for sure is to count either the teeth or tire revolutions (if 3rd member is still installed).

Also, on my 4Runner with factory 31" (well, 265/70-16) tires, the door tag still indicates 225 tires, and I have yet to see one that says 31" (or 265...) on it. If I decode the axle codes from the sticker, it does indicate I have 4.10's (but I knew that since I bought it new and still have the window sticker).

So, the only way to know for sure is to count...
