Were there bubbles present in the overflow tank?
The dark matter in my overflow looked like little tiny particles and did not feel greasy when i cleaned it yesterday. Im gonna watch it closely.

I'd clean it out like crazy and get new coolant/distilled water in there to have a clean starting point.
Does the vehicle have Subaru's required coolant conditioner?
Did they install it properly - shake the bottle vigorously and pour in the radiator?
Maybe they didn't shake the bottle - that'll leak little particle like weird things floating in there. Supposed to shake it.
Automatics do have a transmission cooler passing through the side radiator tank, that is another area where oil can enter the coolant....but I've never really heard of that happening, they make that cooler copper/metal and it's submerged in a fluid where it won't corrode and yours is really new so hard to imagine that happening.

Oil will collect into drops and little pools and float on top of the coolant. It does not mix unless there is some serious agitation going on, but then it will be a nasty brown frothy layer (kinda like a wendys frosty) on top of the coolant. It will separate if left for a long enough period.
