Help! Is this normal?

My brother drives a 2011 Toyota Prius. I’m sure you’re all familiar with the EGR issues. The car currently runs fine, but for christmas I decided to clean his air intake and egr as part of preventative maintenance.

Anyway, when I took off the throttle there was oil in the intake which from my understanding is to be expected due to the PCV. I’m concerned about the color. Is this white indicative of anything?

TLDR: is this white color in the oil in my intake manifold a sign of something bad?
