No. That is not a mistake. Which tv do you have? If you'll notice, the CMS and IRE settings are different (as determined by a light meter and software) and the Cool settings tend to lean more towards the blue end than the Warm settings. Those settings were determined on a 47LD520, but each tv has different tolerances so on yours, the difference might not be discernible. That's why using someone else's settings might not look good on your tv or, as in you case, you don't see a difference.
