This open access article details the developmental maturation of a hormone-dependent olfactory phenotype. Has anyone detailed the  maturation of differences in what mammals see that are not hormone dependent? If so, the biologically based relevance of olfactory input could be compared with the relative salience of visual input in mammals. However, so far as I know, all sex differences in the visually perceived phenotype of mammals are hormone dependent.

A flying mammal that relies on acoustic signaling for food acquisition helps make my case for the importance of olfactory/pheromonal input during the development of sexual preferences. Arguably, if you cannot see that sex differences in other sensory systems result from their association with sex differences in the development of the olfactory phenotype, you might be blind as a bat.
