Because if the losses shown in your graphs are not audible, they are irrelevant. ABX testing tests whether those losses are audible and therefore provides a meaningful way to compare codecs. The graphs do not, or at least, they do not provide a meaningful comparison in the absence of a listening test to determine whether the losses matter.
