So when you say PF48, you are referring to the non ecore version? The classic metal construction ACDelco filter? You might find the linked thread below interesting.* It does seem some interchange of PF48 and PF63 occurred. And as your post proves, that was even with dealers.
And to follow up on 'possibly/likely' not using an ecore as the factory filter on the Corvette engines the linked thread shows a GM factory ACD PF48. If you read it closely the relationship of the PF48 and PF63 is interesting, and somewhat confusing. Took me a while to find the thread of car51 dissection, but wanted to back up what I had posted regarding the FF ACDelco. Realize different model but not huge leap to other similar applications.

Lastly for ecore, if one thoroughly reads my comments about them, main issue for me is the use of a combo valve. In GM models old and new, that not an issue because not used. Newer GM use poppet type bypass on ecore. That said, still ' my preference' is for metal endcap construction.
When I say pf48 I am referring to the size. Basically the model year or two before mine speced the pf48 sized filter and mine specs the pf63. Since the specs between the pf63 and pf48 were the same except for physical size at that time I decided to use the stock of Napa 7060 (pf48 sized) filters on my car since it was new and I change the oil at 5k. This was before the info we know now about why the pf63 came about and at the time it was suspected by the dealer that it was because the longer filter was easier to get off and the Internet determined it had to do with handling contaminates when the timing chains start to let loose at 100k.
Here is the factory filter that came off my car. Pf48 sized dome end relief and no Adbv valve. It says to replace with pf63.
