I wouldn't say that they don't get 'more'... I'm sure there's some form of difference. Often, you can look at the post-game shot chart and have a pretty good idea whether an inside or outside offense was played.
I think it's more 'in general', though, as opposed to being limited to merely PG/SG/SF for outside, and C/PF for inside.
I suppose it would be the same as having a PG/SG driving to the basket while playing look inside/low post -- which isn't unreasonable. But I always cringe when I see my C/PF taking the threes
