Hmmm. For the longest time I would have agreed with you. Then, on viewing the film again a few years ago, something (I can't recall just what tiny detail) made me think this may have also been tied to his comment about "You've done a man's job"... and that Gaff was fully aware all along that Deckard was a replicant (set a thief to catch a thief, as it were), but for his own reasons chose to let them go ... perhaps he himself is one... It isn't stated, but it is a possibility to niggle at one; and fits very well with PKD's themes of confusion between who is and isn't "real", and the nature of reality, how it is defined, where the boundaries lie, etc.
