Yep. The in-a-nutshell argument for AI is that there's an unusual amount of bias and corruption in boxing judges, who usually determine the victor. The in-a-nutshell argument against is that less subjective scoring systems like punch counting have already been tried as an alternative in Olympic boxing, but fans didn't like the adaptations in style that resulted.
(Of course, dropping the punch counting for the 2016 Olympics immediately resulted in subjective judgements that were interesting at best...)
A computer can only judge based on things that can be measured. Martial arts (and really sports in general) rely heavily on things that can't be measured such as aggression, spirit, toughness, etc.
I believe the argument would be that humans are inconsistent, fallible, and gameable in idiosyncratic and individual ways not that they are less susceptible than AI.
