Sorry, I guess what I meant is that this hypothetical ultra-wealthy person wouldn't think "I am going to get a <premium brand> dishwasher, as such. They'd assume it would be the absolute best. If this rich person fancied themselves as a chef, they'd absolutely obsess over the oven etc and have a very clear concept in mind - eg: a high end Aga. But the real estate brochure boast of all Miele (or Bosch, whatever) kitchens would not move them, as such.
