What Lats Do Standard Pullups and Elevated Inverted Rows Target?

I've been hearing so much about this upper vs lower lat workout emphasis. To this day, I'm confused whether standard grip pullups target the upper or the lower portion of the lats. The same goes for the overhand inverted rows aka australian pull-ups?

My question is, what do standard grip pullups target exactly; is it the upper or the lower lats. As for the inverted rows, I know that an overhand grip - which is what I do - targets both the upperback and the lats respectively but what lat does it exactly hit?
