We all also know, that heat raises The oil below is, as said, pumped through the engine and doesn't get the same amount of heat compared to the water...

Thrus oil will also "sit a while" in the sump until it is sucked into the system. Water is constantly pumped around and through out the engine.

If you have never driven a car with a water and oil gauge (in °C! Not just a scale saying "Cold-Warm-Hot") you'll not understand...
Agreed. The hottest place that the oil encounters is turbo shaft and bearings and underside of the pistons.
