Thing is, you get what you pay for. Apple doesn’t cut corners.
But enjoy using a Samsung Monitor with an Apple computer. I’m sure it won’t work as good and is as well integrated with Mac like an Apple Studio Display.
I have an ASD and enjoy it quite a bit. It was the product I wanted, with the features I wanted, at the price I was willing to pay (heavily discounted, of course. I don't pay list price for anything from Apple, ever). I also have a $200 throwaway HP business-class monitor I use as well. Obviously, the Studio Display is significantly better in every respect: Build quality, resolution, brightness, and so on. But they are identical in their ability to seamlessly connect and work with my MacBook Pro.
My wife uses a Dell 4K monitor with her MacBook Pro. She got it for the ultra-wide aspect ratio, which she likes and is useful to her as a software developer. Works great, trouble free. Very nice picture quality. She doesn't understand why I spent about double on my ASD, but she also doesn't really care. Wasn't her purchase.
I don't really care if not a single other person bought an ASD. I like mine, Apple will support it with warranty and software updates for a certain amount of time, it fulfills my needs. I also don't care if it was a "failure" for Apple because Apple's gluttonous profiteering is not really something I enjoy cheerleading for. End of story.
