Here is a comparison i did the other day. My 2017 has 108k. This is off idle oil pressure with the regulator off vs on.

So as you can see. What the pump can actually do vs what it is commanded to do are two different numbers. So if you think you have low oil pressure, the ecm is more than likely putting the pressure low for a reason.
