Your mileage will vary, but I did a small experiment with dry hopping and fining with gelatin a few weeks ago.
I had a 10 gallon batch of pale ale. I split it 50/50 into two 5 gallon cornies.
I dry hopped both kegs the same.
I then added gelatin to one keg and left one keg alone.
I then carbed both beers and did a blind tasting a few days after that.
The beers tasted different.
The gelatin will take some of the hop flavor out when it's fining.
