No. Tony Stark had his character development in one movie. The other instances of his character arc were not part of his main character development which was more or less: "Weapons are bad".

Banner has no evolution to go through. He was shown in the very first movie how he managed to live with his curse. That's all there's for him. Any other development is not part of his primary development.

Thor's development was "Being a selfish jerk is bad." That happened in the first movie. Now he's more responsible. No need for further development.
