Question for makers

I have just bought another piccolo it is a Boosey and Co and it says RS PRATTENS perfected. I always thought going by the conversations on here that Prattens were big holed?

Anyway i have another Piccolo which has bigger tone holes than the Pratten

My question does a flute that has larger tone holes play louder on the bottom register and the flute with smaller tone holes play louder on the upper register?
