The difference would be not behaving as Korby would. That was a point that the episode made. The whole idea of creating a race of android duplicates covertly "infiltrated into society" as he put it was one that the real Korby never would have promoted in the first place. Ergo, the consciousness in the android was not an exact copy of Korby's, probably for multiple reasons.Here's where I have to ask - what would the difference be?
Whether Korby's essence is indeed transferred (whatever that means) to the android body or just receives an exact copy of memories, he would still think he was the original - and with the original organic Korby deceased there would be no-one around to question the validity of the process
Chapel was there to referee that he wasn't the real Korby, as she did.
