"Everything meshes with my chosen wallpaper" is a common aesthetic interest, that the article author dismisses because they don't care about it and mostly don't notice their own wallpaper, but if you look at certain subreddits and "Life Hacks" forums you'll find lots of people with heavily customized Android icon themes or deeply complex configuration of iOS shortcuts to aesthetically align everything they want on their home screen.
