Any chance it could have caused the oil light to flicker a time or 2?

What oil and filter were you running when the light flickered?
Only one possibility that I can imagine, and it's just an wildly uneducated theory.
I saw a post years ago on a board where a guy was fighting a cam timing correlation error code, and after ruling out the VVT oil control valve, actuator, and filter he found a sludge-clogged oil passage in the head casting which blocked the VVT oil return circuit...so the VVT actuator couldn't de-pressurize when the oil control valve closed and his timing was staying advanced.
So...if you had a defective oil control valve with the spool valve improperly controlling oil flow, and it malfunctioned in such a way that it directed oil to dump down the return path, it could possibly drop oil pressure given the lower flow resistance. Again, just a complete guess and I have no way to know if it's even possible.
