It depends if you are referring to aiming high or low because you are worried about point of impact changing when shooting from elevation.

OR

If you are talking about the actual spot on the deer where you want the arrow to enter

If the 1st option...you should not need to compensate if you use proper form. But as suggested, shoot from elevation & see how you do

If the 2nd option, when you are up in tree, you WILL want the arrow to enter higher on the deer than if you were level. Just the same as when the deer is angled away, you want the arrow to enter slightly back compared to when he's broadside.
