I made a cover, using the scan from
Bear78.
Horizon Zero Dawn - Complete Edition (NTSC)

What do you mean "normally"? The only difference between raws and finished covers are cleaning up the covers, by removing dirt and scratches, and straightening the cover.
It can be a lot more work, even with a good scan.
Many covers on here are not even cleaned up raws, but partial or complete recreations.
In this case the scans from Bear78 are pretty clean and mostly straight. But they needed a lot of color correction. I put an example below.
Left: Scan,
Middle: my edit of the scan,
Right: a digital Image of the cover from the publisher or what the cover should look like.

I think I got it close enough...
