Is there a quick way of estimating the difference in frequency
response, demonstrated by a 100mV difference in rising edge amplitude
of a 2Vppk 1KHz square wave?

I know the rise-time requirement rule of thumb, but never stopped to
consider the other, though probe compensation is one of the first
things you run into, with normal scope use. Just never stopped to
consider....

Simple spice calculations show that the simple compensation scheme's
of 200MHz probes cannot produce overshoot with the time frame
illustrated in the pictured 1KHz calibration signal - it should
normally be all over and done with in the first 100uSec of risetime.

Someday this post may actually make it through the frigging primus
