Hello there
It will get more slouchy it might even be stuffed in the photos ask the seller
Cleaning and conditioning information can be found in the thread in the reference section on that topic
The darkness on the corners probably are not going to clean off probably it wear with color loss
Color restoration on dark areas with lighter colors can be difficult I’d say use a professional on that
The sheen ? I’d ask the seller it could be the photo lighting or it could be an after market shine spray or something else.
All the best
Doc
I've look at your leather care recommendations thread, but did not see anything on swift. Did you use a different term for this leather? Thanks!
