I know you're referring to the materials. And I'm saying you can find those same materials in Android phones.
I'm used to actual luxury goods, watches and clothing for example, where the quality is very much noticeably better. A Rolex or Audemars has way more attention to detail than, say, a Tissot or Tag which has far nicer materials than a Timex. Or suits, the kinds of fabric on higher end suits are very noticeable.
Or luxury restaurants. Where the ingredients, techniques, staffing levels and attention to detail far surpass normal restaurants.
Whereas with iPhone versus Samsung S24 Ultra, both are titanium, Samsung has nicer glass, less bevel and more utility (also costs more). The only real difference is Apple has much better marketing and their stores are nicer. Better logo too. Beyond that, there's no quantifiable quality advantage.
