Here's the definition of exposure which I am using: the combination of shutter speed, aperture, and ISO which was used when creating the photo. That is all -- and I believe that that is the standard technical meaning. Sometimes it is used casually to refer to the overall level of brightness, but that is casual and not the actual meaning.

So, using the definition above, changing the color balance does not change the exposure. Applying an auto levels or auto exposure adjustment is indeed post-processing, and does not change your shutter speed, aperture, or ISO -- nothing can change those once you have taken the photo, whether raw or not.
