Nah, Zara's case is far far more scummier than Conquist's.
It's not just him not getting a clean result, it's his playstyle overall, his vote hopping on day 1 to save himself was scummy first of all. His vest up on N1 was again scummy, which btw, I don't think he vested up N1. He probably visited Dyna. Now, his ability claim is apparently not as legit as it should be since both Krogo and Dyna say that the ability description doesn't fit the ability name.
So it's not just Zara not getting a clean result on Tobi, it's Zara's ability claim itself being doubtful here.
Thing is if Zara is A who wants to investigate B and if B is swapped with D. Then all of B's visitors go to D. That means Zara, Prof and Rej should all go to D.
But Rej still didn't see Zara visiting whoever Tobi was swapped with, but saw Prof.
