Colored Leather Case Patina?

I bought the Dark Aubergine (Purple) Leather Case for my iPhone X, and I love it.

However, I was wondering if it will ever develop a nice patina? I know the blue does and the brown obviously looks fantastic, but I'm not sure how these colors are applied to the leather and was hoping someone could verify if the purple would or would not change at all.

I had a black leather case for the iPhone 7 and it didn't - most likely because of how dark it is, so I was hoping this one would.

Thanks!
