I think maybe YOU'RE overthinking this.
I doubt there's much temperature variance anywhere in the liquid
oil once an engine is warmed up. The film on the walls of the cylinders, etc. might be hotter but I'd bet that if you had sensors in every part of the liquid, it would be within a degree or two. (The downstream line from the cooler being the exception.)
The magic 80* is the point at which
oil cooks off moisture and vaporizes it, meaning it can be removed by exiting the breather or (better) being pulled out by the PCV system. Any lower and the vaporization will not be as complete.
