^ The fact that the zipper is white or plastic is not the issue, actually, because the "original" bag does have a similar interior. But I think it's apparent in the photos you've provided that the zipper used there is very low quality, the fabric around it is the basic fabric that comes with low-quality zippers and the "metal" part doesn't seem to be metal as it doesn't look heavy enough.
Also, the bag Chanel has with such lining is the Reissue Executive Cerf Tote Shoulder Bag. I can't seem to find a different Chanel bag with such an interior.
