I fail to see how natural energy would make the rest of the chakra invisible. Well think about it. In chapter 610 and episode 363, Kurama stated that: the Ten Tails "couldn't" be sensed through traditional chakra sensing "because" it was made of natural energy itself, that and you can't sense negative emotions from it because it doesn't have any emotions. The point being if natural energy can't be sensed by 'ordinary' chakra sensor types, then that 'might' also mean Senjutsu chakra can't be sensed through regular means because it's nature-based along with the other 2 energies chakra.
