Yet another LFX oil pressure question

Changed the oil today Mobil 1 and it seems the warm idle oil pressure has slowly diminished over the past couple years, about 3k miles in those two years. Oil changed annually at least though. Oil was dark like a normal change and not gritty.

Gauge pictured at warm idle with about 12-13 psi. When I installed gauge cluster a couple years ago was around 20-25 psi.
Picture at just 1000 rpm's with around 22 psi also warm. Pressure increase like normal with higher revs.
Cold start up I get the usual pegged around 70 psi and over 50 psi when driving around 1800 rpm's after warm.

Read as many threads(couple below) as could on this and some say only need 10 psi and others mention having around 30 at idle. Didn't find anything definitive though.

Car has 36,000 miles with bolt-ons and catch can.
I empty the catch can about every 500 miles has the usual couple ounces of gunk. Car maybe uses around 1/2 quart between oil changes. Never run low on oil thanks to all the tips on here about checking it regularly.

Should I take it to the dealership and have it checked out before damage occurs? To late?
Should I be concerned?

Side note I had been taking it to dealership for its free oil changes until now. Not sure why I never thought of it but didn't ever ask for a good synthetic when they changed it.

I'd hook up a mechanical gauge to check for accuracy.

Thank you. Was my next question if that was possible with these. If it was a 1970's car would have been one of my first thoughts. Some reason was an after thought with the Camaro. Still learning about these DI engines. Thank goodness for Camaro 5.
Will try post results and hopefully some pictures.

Thanks again really appreciate it!
