Jobs cared deeply about the details, both UI and UX, it's just that the details he cared about and how he prioritized them might be ones you and me disagree with. He almost never sacrificed form for function, but he certainly did care for both.
That attention to detail was one of the reasons people loved Apple products and why so many Mac-only or truly Mac-native apps exist. Contrast with windows where most "native" apps are either Qt-based or some WPF monstrosity full of custom controls. Microsoft Office has its own UI stack ffs.
That doesn't mean his vision was always good though, or that he was a good designer (he was good at picking things and making sure they fit, but he didn't come up with them himself)... Some decisions are just baffling to me, seriously how long did macs stick with 1 button mice?
