I don't wanna rain on anyone's parade, but your "read out conclusion" is well, just an assumption.
The so-called 'gauges' on these newer vehicles are little more than a pretty "everything is okay/don't worry 'bout it" icon on your dash.
Nothing more than a modern version of the old idiot light and have very little to do with real oil pressure values going on in that engine.
Once the engine starts and the initial pressure develops (usually about 8 lbs), the computer takes over and throws a 'random/good/it's okay' figure/dial-sweep at your eyes just to make you feel all fuzzy and warm inside. A comfortable 'stroking', if you will.
Hard wire a good old fashioned gauge into the engine oil galley and you'll see there is absolutely no difference in oil pressure due to a different filter. None.
The physical filtering circuits are a bleed off oil, seconday to oil lube circuits and they actually only run roughly 5-10% of the oil volume pumped thru the filter.
Don't take my word for it; ask any factory trained tech. You're seeing what the computer wants you to see.
The fact that you're seeing a difference between filter A and filter B reinforces my point. The sensor is located/reading a filter circuit and not the engine oil galley pressure like you'd think.
