Depending on where your sender is, it will either read the same or 2psi higher. This assumes that your oil pump is out of relief (not at peak pressure).
When your oil pump isn't in relief, the filter can not change flow. Since the flow is the same, the pressure downstream of the filter must be the same (at whatever that pressure would be at that flow rate - at that visc). If the filter presents any "pressure drop", it's really an elevation upstream of the filter. Up to the point where the pump reaches a pressure limit and starts to shunt flow back to the pan or suction side of the pump.
This assumes that your pump is of typical mechanical efficiency.
If you see reduced pressure due to a change in filters, you're either at the relief threshold, or your pump leaks (usually at lower speeds) enough to show a difference. This could be part of the design characteristics ..or it could be worn. The test I use to determine either is if the same characteristics are wide spread across all units. When someone reports better pressure with one filter over another, and thousands of other units don't, I tend to lean towards the worn pump theory.
..but ..and assuming no relief event is in progress ..and the pump is of typical efficiency, most filters are next to invisible under most conditions. Conditions and restrictions apply and there are always exceptions.

Should I even concern myself with such a matter?
No real need to ponder it much. As long as you leave the in block bypass intact you should get your desired results in a totally transparent manner.
So, don't worry, but many here like to ponder such things a good bit
