In some cases this is quite explicit (eg the multiply > blend mode), and sometimes we try to hide this (eg contrast). The You can of course use something like an RGB to L*a*b* conversion purely as a mathematical transformation to allow certain types of adjustments without regard to the color meaning, but my suggestion would be to never call the resulting space "Lab" if it is not a genuine device independent color space. You'll just confuse and mislead anyone who knows what that's meant to be.
