I don't think there are many truly luxurious options in the category of everyday items. The ultra wealthy have the same options as the middle class in terms of apple corer, mobile phones, tablets, toilets, or streaming services.
Luxuries would be things like hiring personal assistants, hand-made/customized items, art collections, etc. An emperor wouldn't have a golden hoe, because he doesn't farm.
Michael Bloomberg had a $13,000 bespoke bathtub made of hammered copper by French artisans in Villedieu-les-Poëles near Mont Saint Michel, the only place with the skills to make such a thing. Copper conducts heat very well so it takes the temperature of water immediately. No cold bathtub walls for Michael. Compared to the $8K mass-produced toilet, it almost seems like a bargain now.
Mark Zuckerberg practicing jiu-jitsu is an example. Gym participation is a luxury display of leisure time. I wonder why he didn't take up golf. There seems to be a trendy desire to leisure train physical fighting ability as opposed to other recreational activities.
