That is true, it doesn't mention the effects any weapon upgrade has either way. Just going from my own experience here; I have not noticed any change in damage output after weapon upgrades. Let me translate that to what it really means; I don't pay attention to my NPCs damage output.

The thing about weapons, is the weapon you give is not what she wears. And some weapon upgrades are the same level as the weapon they have (for example the last two G.Axes are both 34). IMO, the weapons serve as a NPC bond boost, and an NPC visual upgrade. That's just an opinion, I could be way off track.
