I've made it a hobby to compare my current standards of living to "When would this be kingly?" We've traded down so much on quality of products (and sometimes: quality of life) but making a conscious decision to "live like a king" in a lot of cases isn't that hard.

Simplest example? Indoor plumbing: Boom, 15th century king.

Silly example? I got my wife seven silk pillow cases one year as a Christmas gift. A bit spendy, but instantly "living like a king".

We don't have "the royal kitchens", but do have Door-Dash. We took a tour of a castle somewhere in Canada (probably Craigdarroch) and they had a bunch of sitting rooms and reading nooks with extra lights and stuff... Steal Those Ideas! You too can live like a king, you just have to rewind a century or two, and be strategic about the luxuries you pick.
