Looks like the corners were worked/laid down, pressing being one way to accomplish that. Depending on the degree of corner lift, sometimes it’s as simple as the grade school method of putting a card in a thick book and sitting on it LOL. Worked for me with a Wade Boggs RC in 1986!

Is putting a card under heavy books really considered altering a card?

I had a horrible situation where a BGS 9 1982 Wrestling All Stars Andre The Giant was lifting in the slab in the mylar sleeve and I had to crack it out to rescue it.

One of the corners started kind of bowing upwards with no actual damage and I put that card under a bunch of heavy books for a week or so to try and flatten it back out and it now resides in a PSA 8 holder.
