On the Paleto Score, does the death of the gunman changes gameplay of the mission?

According to the Fandom page:

If an unskilled gunman is chosen, he will be crushed by a police car [once they enter the construction yard]

and

If the gunman is alive, he'll help by distracting and holding back some of the soldiers outside [of the chicken factory]

Does this changes the playthrough of the mission? (like enemy count and the speed that takes for the train to appear)

So far, I have not seen changes between a good gunman (Packie) and a bad gunman (Daryl).

It makes the mission slightly harder (as you'll have one ally less shooting back at the police) and results in a loss of profit (since the money the gunman carries is lost).
