It's even more complicated than this.  Many Windows users have never
adjusted their monitors and have horrendously low brightness settings, not
to mention the fact that yet more users do not even know that they can set
their monitors to display higher than 8 bit color (256 colors).  There are
so many variables to this equation that it's not worth pulling your hair
out: optimize for the majority of your audience (which will probably be
mostly Windows) and leave it at that.

Also, remember that it's unlikely that users of one platform will be able to
compare one gamma display against the other -- without any point of
reference, they won't know that any difference exists.
