The point is, by definition, a "confirmed theory" is as high up as you can get.
There are no "proven theories."
A theory can NEVER "graduate" to become a fact (confirmed observation) or a law (mathematical equation).
A scientific hypothesis, if confirmed, becomes a theory. It may later be modified or replaced by some other theory, but theory is what it is, and always will be...
At least, that's my understanding. Maybe someone else understands these things better than I do?
My post had a smiley, indicating sarcasm.
