You know if I recall correctly Kaku and Kalifa were given unidentified devil fruits and "learned" the name upon eating it. Did the fruit lie to Luffy?

We have never really been made clear how much knowledge you get upon eating a fruit. I always assumed Kaku and Kalifa ate their fruits, saw what the basic power was, then looked up what else the fruit could do (I'm guessing the powers had been seen before but what the fruits looked like is less likely to be known). We know books on devil fruit abilities exist and surely CP9 would have access to one.

Chopper didn't seem to know he could transform at first. Pretty sure Luffy is told by Shanks what fruit he ate.
