Code Beautification is a waste of time and ossifies a code base. It's a form of optimization that actually makes the code harder to change and the business less agile. It is pretty though.
Beauty for the beauty's sake is art, not business.
Usually simple, lean, and logical is also beautiful; beauty is not a random quality. But sometimes too simple and too lean is not flexible enough; then that's a case of a wrong abstraction, or of premature optimization.
