Make sure you choose the most accurate pre-set picture mode before you dive into the calibration. Usually we pick Movie/Cinema mode. If you are using any other mode, there will almost always be a heavy blue push. And pick a color temperature that is the closest to 6500 kelvin (usually warm 2). That being said, it is always better to have a blue error vs red or green. But since you are doing a 10 pt adjustment, you should be able to nail down all errors if done correctly ofcourse.
