Jurassic Park did popularize the relatively new idea of dinosaurs being related to birds with the public, which is pretty awesome. They also made us finally forget the image of tails dragging on the ground as the default. It wasn't as accepted that many dinosaurs had feathers at the time, with it still being likely that the biggest ones had very few in the same way that elephants don't have furry coats.

They intentionally altered with the dinosaurs' designs to make them better monsters. They reshaped the t-rex's skull and teeth in a way that would have made it a less effective hunter, just so it looked scarier. They turned the dilophosaurus into a spitting cobra because it was cool, and made velociraptor way bigger because a human sized intelligent monster is a fantastic movie villain.

I think feathered dinosaurs will become the norm in movies because they are so freaking cool. Jurassic Park made them cooler by being more accurate to what they were actually like, so a new successful blockbuster will eventually update dinosaurs with all the cool shit we've learned since then.
