short version (if i have time , i may come back and expand on it ore later today) :
if the card is not a high grade (at least near mint or better) , but merely slabbed for authentication/protection and does not have a GRADE , then by all means you should describe the condition of the card in detail....even cards NOT encased , it is often difficult to get a scan to show all the defects such as chipping or surface scratches/wrinkles.....when they're in the thick case , an accurate 2-d image is even harder to get....
anytime i sell anything less than that condition on ebay i am VERY specific in detailing any flaws i've noticed despite having at least one high-res scan .....in my experience , even with huge pictures and detailed descriptions (which include the specific comment that the card is damaged) i have had a few buyers who didn't pay attention and after buying off-grade items e-mailed me commenting that the card was not mint.....
in short , ALWAYS assume the buyer isn't paying attention and provide as much detail as possible as a way to CYOA in any SNAD claims.... far better to overestimate the damage and drive off a potential buyer than to downplay (or ignore) it and wind up with a picky/impatient/unreasonable buyer who slaps you with negative feedback etc.....
