That's right if you use gamma correction purely for the purpose it is 
intended for (i.e. for compensating the monitor gamma).  A lot of people 
however use it for artistic purposes just like the clipping.  It is 
still fairly common for example to design scenes to show up correctly on 
a certain monitor without gamma correction.
