Off White/Light Colored Cervo Leather questions

I have a white cervo bag from the last summer collection. It hasn't picked up any denim transfer, but it has picked up color transfer from my shirts -- the opposite of what I was expecting. The bottom has also gotten rather grey, even though I've been careful not to put it anywhere that looks dirty or dusty. But you don't really see that unless the bag is empty and laid out flat. (Or maybe if you are a very small child standing under my bag and looking up!)

I've had light colored BV bags redyed before. They can't all be redyed since some color are seasonal, but I was told my bag is a permanent color so it can be redyed. I think the color name is Platre.

I really like my bag. I love light colored bags and I knew when I bought it that it wouldn't stay pristine. I'm not bothered by a little wear. However I am careful to not use the bag when I'm wearing dark colored or neon shirts anymore.
