The perception of realism would still matter.
Just use test audiences to see what people believe looks the most real.

Also, a realistic T-Rex may never survive in our modern atmosphere. Those lungs are so large because O2 content was about half of today's (http://www.firstpost.com/tech/news-analysis/atmospheric-oxyg...) and the mix of dinos they have in JP is just a mess of evolutionary reality.
Trying to say that the dinos are realistic is just crazy. Maybe, kinda, in the first one, they were, a little bit. Even then Jack Horner got a lot of flak from the community over his consultation on the films. But the evidence we have now just points to a much different creature than what we though of even a few years ago. They aren't monsters, just standard terrestrial vertebrates trying to make their way in a different world. We have so much to learn from them, about climate change, about physiology, about adaptation, etc. So trying to keep the monster and the known 'reality' separate is a big deal to me.
