Well, outside the show we refer to Pearls by their color in order to distinguish them from each other, but in the show the Diamonds and others simply call them "Pearl" when addressing them directly or as "[owner's name here]'s Pearl" when talking about them.

So while I am not ruling out the possibility that Pink and White switched Pearls, I don't think Blue's statement indicates this.
