High and fluctuating oil pressure

I just had my first oil and filter change of 2015 JGC at 3000 mile. Now when the engine is cold, the oil pressure stays above 80psi with occasional quick drops to 40 psi. Only after engine warms up, it gets stable reading around 40psi with 27psi at idle sitting in traffic. If my memory is correct, I never saw this erratic and high pressure before the oil change. Has anyone experienced the same thing? I wonder what could be the problem. Could this be a clogged filter?
