The reason why I ask is that I have noticed that one or two of my razors seem to get more comfortable after using them a few times.
AHA ! "Taping spines & can my razor be too sharp ?" This thread could go long time

So there is a physical limit to the width that most blades can get . There was a pdf floating around on the net by Verhoeven with pictures & numbers. I won't trust my memory to quote but it was fractions of a micron.

Can you shave with the thinnest edge possible ? Sure. These are the razors that will teach you that an almost flat contact is best. No 30º generalities here .
Will you get bleeders ? Most likely, when you lose concentration for a split second. Will that edge still shave nicely if you tone it back a bit with strop or stone . Sure.

It's all about your skill & your skin & whether the steel can be honed to that degree.
