It can't absorb Space-Time Ninjutsu, as in cases like Kamui, there is no chakra within the distortion itself, but within the user, which is consumed by the technique to create said distortion. It also shouldn't be able to absorb the Truth-Seeking Ball, unless said Preta Path user is also using Senjutsu to enhance the absorption.

Personally, I think there is a limitation to the absorption in the form of range. I think that should a Dust Release used surround a Preta Path user in a Dust Release cube the size of the ones used to obliterate the Wood Clones that used Susanoo, the cube and its core would be out of range of the Preta Path's absorption range. Thus, they can't absorb the technique before, during or after it detonates. But that should seem pretty obvious to those that pay attention.
