We see this problem within the first few days of nearly every peice released and not just speaking in terms of PCS.
I am still amazed when I see people with old join dates and/or lots of post....you should know these things by now.
If ANY piece looked AS GOOD in a pic as it does in person...we would all just buy posters / prints.
Lighting, angle, camera quality, filters, focal distance...all these things play a role.
If you never seen any of these pieces in person or if these were the first pics you have seen of them...you would probably think all these pieces have bad paint and are probably washed out.
