Almost. The response curve of the scanner can be any shape you like to suit your output media, or it can be perfectly straight and linear WRT the piece of film being copied. As much as duplicating films and internegative films are meant to have a linear response, in practice each individual camera film has its own characteristics and the copy films are either optimised for one or are a compromise to acceptably suit as many as possible. Apart from simply changing the filter pack on the duplicator, this is done by either choosing a different brand or by tweaking the process.
The biggest problem with copying films is that different brands, even different types in a single brand, have dyes that your eye perceives differently to the way the copying emulsion does. It's not so bad now that E-6 is practically universal and AFAIK C-41 is universal, but brand differences still show up.
