In my own collecting experience, I've seen enough scans at various auctions of lower grade cards to know that a scan can more often than not fail to present the full picture. In reality, I would imagine an AH simply scans each lot and moves onto the next scan, rather than scanning a card and pausing to evaluate whether the scan adequately showcases all the card's flaws, and then re-scanning or adjusting settings to accomplish that. I'd therefore simply put some onus on myself as a shopper if I was interested in the item, and call or email the AH to ask for some more details or images.

So yes, it could be any range of creases or wrinkles and learning the precise degree of wear would matter a great deal; I'd choose direct communication with the AH about the lot as the best route to obtaining that information.
