UI based on individual data / dynamic / generative

I am looking for examples where the UI is designed based on the individual user data. Not just a customizable profile page, more automated individual color palette / layout / typography / ??? depending on individual user attributes like age, friends etc.

Do you know any examples in that direction?

edited for clarity:

on the apple app store, some apps have a unique page which is derived from the color palette of their app icon. Imagine your Facebook ui would look different from your friend's in terms of color, layout / size and placement of ui elements, typefont – and all of this would be derived from your profile data. you are from new york – times new roman, you are from LA – Helvetica. you have 516 friends – red primary color, you have 1208 friends – blue primary color –
