Well, as I pointed out somewhere else, suggesting “I came, I saw, I came” in English as the name of a strip club or whorehouse is by itself pretty much the whole joke, and people don’t need to know Latin to get it (to get “Veni, Vidi, Veni” one needs to know both the original expression in Latin and that the word “Veni” means “(I) came”), exactly because as you say, pretty much everybody knows “I came, I saw, I conquered”.
Putting it in Latin for me feels more like a way to signal one’s above average educational or cultural level, that anything that enhances the joke.
Next to none of us know Latin, but we pretty much all know “I came I saw I conquered”
