This article argues correctly (here and in other articles on this site) that the single channel, white-balanced histogram is insufficient to detect hilight clipping or channel underexposure.
However, the table in this article is (as Peter points out) not comparing to ETTR but rather ETTL! Which will of course give the noise problems you mention. Underexposure is exposing to the left.
