Could the pressure relief valve be causing this?

If there is an intermittent problem with the gauge shifting its reading, it will still respond to the engine rev. Just because is responds to a pressure change, it doesn't mean it is functioning perfectly.
Certainly a PRV issue could cause a pressure change, but before I tore into my engine, I would make sure there was a real pressure change. The very first step is to verify that the
oil pressure is indeed changing, as your gauge indicates. Or you can be like my brother n law. He replaced the engine in his wife's car, just to find out it had an empty gas tank.
I learned a long time ago to assume nothing. It could be many things. You have to start somewhere and prove what is or is not. In your case, I would start by proving that the pressure gauge in the car is correct or it is not correct. Then move forward. But if you are looking for an excuse to tear into the engine don't let me stop you.
