Although these changes may seem like an unnecessary level of attention to detail, its important to keep in mind that this would be a very minor change to make design and engineering-wise. We're not talking about moving around elements or re-doing the entire design, just changing some colors/gradients. In my opinion, the little bit of extra effort required to put this level of polish on a product is completely worth it.

Most problems with perfectionism in design and engineering come from people making bad decisions early on in the design/development process and not realizing that something is fundamentally wrong until much later on--when its much harder to fix.
