If they're identical, and the object is gray, then you've achieved neutral color balance for a gray object. If the object is not perfectly gray, then the colors should not be close to eachother.

Not really. The goal for neutral white balance is to equalize RGB values for neutral things (gray card, white objects, etc.).


Of course, if you shoot raw then you can change your white balance in post losslessly.
