No, there are special fireworks for the 4th. The past few years, DL has shown the patriotic fireworks July 1st - 3rd so that the crowds for the 4th wouldn't be so bad.
This was probably about 5 years ago that they were canceled at the last minute due to wind. If you really want to see fireworks on the 4th the safest bet might be to find a show near the coast that is less likely to have to cancel. While it's only happened once that I can think of in 10 or more years, there is still a chance.
