I think that might be because the image is already changed. I get that
impression from Wayne's comment on the "OK dialog" that it was unnecessary
because RGB images brightness and contrast adjustments change the pixel values
directly.
 
The Apply button, however, does something: it redraws the transfer function
and the range values of the small histogram in the B/C applet.
