Do you mean the difference between the two collar sides of where one side droops or hang down lower between the shirt opening placket with buttons and the placket side that has the holes for the buttons?
If that is what you mean: somewhat, yes, the side where the placket is under another where the buttons are sewed on stays up a little higher than the other side where the placket has holes for the button.
It's hardly noticeable on mine. My guess, is I suspect that maybe it depends on the fit of the shirt around the chest- it can influence the material to stay up or droop down on both snug/tight or relaxed/loose fit so I just leave it the way it is on the shirt fit I wear, but none of them has any terrible droop.
Also, I'm not sure starch is a good recommendation for any synthetic material.
Hope it helps.
