Hide is a lot like hair. On average, children have more finely textured hair than adults, but there are also families (including the adults) with more finely textured hair than others.
I think of vellum in much the same way... as the finely textured version of parchment that is more often found in younger animals or in certain species.
It's not a black and white issue, but a gray scale, which is maybe why the definition isn't quite so hard and fast either. At what age does the skin of a certain animal toughen up? It depends on climate, diet, age, and individual differences and, of course, on species.
