You exposed the D4s for longer than the D4

I' sorry but your comparison is pointless as your exposures are different - your test wasn't properly done.

In both cases your D4 exposure was shorter i.e.. 1/125s and 1/500s for D4 vs 1/100 s and 1/400s for D4s.
Check your exposures - you are giving longer exposures to the D4s than the D4.Since this is well into digital gain territory, when you equalize brightness, you are effectively lowering the D4s ISO.
