Ford 3.5L Ecoboost / Kirkland 5w-30 / 2.5k miles /

That original sample is most likely a dirt track engine. Those Zinc/Phos/Calcium levels are what you would expect to see in "racing oils"

I just read they mixed samples, which was starkly obvious from the DP/AP metals.
I was going to say - cut open the filter neatly (without undue debris generation) remove the filter media
spread it out and look in the pleats,
I would do it anyhow - that's where the big pieces end up with or without impending doom looming.

Glad all is well.
