Some of these are actually pretty attractive and don't appear to interfere with the usage of the app. Others aren't so attractive and many more are hard to use.
Why is a texture automatically worse than a solid colored background?
I wasn't arguing that texture is worse. When used appropriately, it's generally better than solid colors, both in terms of UX and just visual attractiveness.
But there is a certain category of textures that seem to come up most often on this site. Things like leather, denim, paper that perhaps remind users of rough, tactile, durable materials. These metaphors get a lot of use, especially on iOS, and I find that it's funny to call them out sometimes. Sure, it's attractive, but also perhaps a bit derivative.
