Yes, some live events are geared towards aging audiences with the treble tilted up, the same trick that some recording engineers also use. I have also been at poorly produced live shows, that doesn't mean adjusting the sound one way or the other is neutral.
My point is that neutral sounds neither rolled off or tilted up, the presence region is neither enhanced nor hidden. Neutral is not thin sounding, bright or weak. Electronic adjustments are made to accentuate detail that lead to this phenomena. Neutral is natural sounding.
It is easier to judge the sound of live performances without amplification or speakers. Something like an Orchestral performance. I have never heard live, unamplified music to sound weak or thin. As always, YMMV.
