As an aside, I was out in the fatty the other day and deliberately made the ABS kick in on the snow/ice roads for long periods as a means to get the pump working. ( on a private estate road which was downhill slightly, so I could keep it skidding ). I noticed that initially the pedal had a little give to it, but as you pressed down through that as the pump was working, the pedal became solid and had no give.

Since that, I would say that the general pedal feel is slightly better and slightly firmer … it’s not much, but I would say there is a marginal difference for the better. So maybe it has purged air by running. V8 or else ...
