...Seems I read Motorking had said the Fram Pro was transitioning to the standard Extra Guard filter since the split from Champ?
He also posted twice, once months ago, that AZ standard blue STP oil filters had been offshored. As of a visit to AZ two days ago, STP blue OF still previous old fram filtration filters with manufacture dates into late April. No change over in any applications in area AZ from previous manufacture/construction or coo. And, the STP S3614 is still an ecore, while S2808 is fram fiber construction. So that indicates those to be still previous ff construction here at least. So the STP S3614 excluding the can color, identical to the linked RA3614 the OP posted. Which is the reference I used.
Now it's 'possible' the OP might get a 3614 with fiber endcap construction, but that's not what's pictured and my reference. My speculation based on the STP filters at AZ here being similar to or same as WM TLE (excluding can color and texture) and the RA picture, it's an ecore. Though the latter not noted for 100% accuracy.
As for the ecogard, what I posted in response to the OP query is factually accurate. Perhaps all aren't that way, IDK. But imo say safe to say based on the anecdotes posted they are having an issue with rust and rustproofing, some worse than others. So, 'I'd' pass.
