Is there any other way to illustrate the overlap of subsets' distribution (not
necessarily by an estimation plot but by a plot of true values)?

I didn't open your attached fi
histogram (without exceeding the max of historgram on y axis)?
Is it more clear?

very small
variance (which might happen), you'd get a very high estimate at the center.
