Did we learn anything from the review that was not overturned?

After seeing the review that Lovie threw on the completed screen pass, I thought the evidence was fairly clear that the pass was incomplete, and was surprised that the call stood as called.  Did anyone here see it differently, because if not, I  wonder if this is a signal as to what is to come when it comes to overturning a call.  If so, then things better go both ways when there is a close call that goes the Bucs way even if it is 70-30 that the call was incorrect.
