I don't know this.

Excuse me, but what is the relation with the black point:helpful

Well, when you're on an LCD monitor, you have a certain level range (0-255) which you can't go outside of.
So if your black point (of 0/0/0) is too red, the logical thing you'd have to do is decrease the red channel (-5/0/0). However, this is simply physically not possible.
To compensate, to fix the tone balance, you have to increase the other channels instead, eg. (0/5/5).
However, this results in a “brighter” black than 0/0/0. In other words, fixing the black point's
tone balance can offset its
luminance (brightness).
That's why the luma error increases.
