To find the under/overflows in a TH3 (same in TH1, TH2), call
h.GetBinContent(i,j,k);
with i=0 (or/and j=0 or/and k=0) for the underflows
with i=NX+1 (or/and j=NY+1 or/and k=NZ+1) for the overflows,
eg
h(0,0,0) returns the number of underflows in x,y,z h(0,j,k) returns the number of overflows in X for bin j in Y and k in Z
