There's still differences. If you're running it in prod then the functionality has at least gone through code review and you have higher confidence what's running is what you think it is. If you run things from personal boxes there's always the risk of them not having the latest code, having made a local change and not checking it in, or the worst case of a bad actor doing whatever they want with the privileged role. But if code review isn't required or engineers have unrestricted SSH access to prod hosts then it's pretty much equivalent.
