So I wouldn't make too much out of a demonstration vehicle's tires being inflated to 50 psi.

I have heard that and it makes sense, but I have also heard the opposite that some car dealers underinflate the tires a bit so the car rides smoother during the test drive. I guess it depends on the dealer.
