Now at 6"WC vac (sump pressure) water boils at approx 195 deg. Is this why our cars have a 195 deg stat stock?

You are overlooking the fact that your oil is always hotter than your coolant, otherwise an oil to coolant cooler would not work. Even in the dead of winter, your oil is hotter than 200F, even with a low temp stat and the larger oil cooler. We have customers running low temp stats and using the cars in zero and sub zero F environs; UOA's show no adverse levels of water our fuel contamination whatsoever.
