My 2019 BRZ still with its factory alignment, the outer shoulder of the rear tires makes less contact with the ground than the rest of the tire (Michelin Xi3). I can tell by how much road dust sticks to the tire tread, and how little wear there is on the outer shoulder. And this is with stock rim, stock tire size, stock tire pressure (35PSI), stock suspension; car has only 7000km.
The front tires however have virtually zero camber from the factory and they have an engine hanging over them so yes there is a lot of sidewall flex, resulting in even tread to ground contact more often.

I run 30-32 psi in my summers (currently RS4's) and 35psi in my snows (currently iPike RS'), and you can definitely see that the snows make better contact while resting than the summers. Same weight distribution, same alignment, more pressure in the snows.
