We tend to operate this way. From the outside everything is tasteful, well-kept and maintained but nothing is flashy, especially our cars. If you come in the house and look closely you will see it but most don't even recognize it because they have never considered upgraded finishes. The appliances are a little obvious but the cabinets are not as well as the flooring. One rule I have told our architect is no extreme crown molding and other finishes that provide zero functionality. Windows are top-tier but you wouldn't know if unless you know it. The best stuff is often stealth because you're paying for functionality as much as appearances. The door and cabinet hardware is top-tier but doesn't look like it unless you know.
I find that top-tier finishes tend to function better, last longer and feel nicer when interacting with them. Things like cookware, if you shop carefully for the high-end stuff is just better to use and more enjoyable in a subtle way while not being flashy or obvious.
