It depends what speaker it is driving. For anything other than a tweeter 100mV would do no harm. A big sub would even tolerate 200mV.
The "damage" could be a slight shift away from the normal resting place and tiny reduction in excursion one way.

But usually, an excess of 35mV denotes either a bad design or a faulty amp in need of adjustment.
DC offset abive 35mV can also increase THD and other distortions but its at so low levels that the natural distortion of the speakers themselves would drown it out and make it inaudible, unless the cone visibly moves out of center.
