For sure, but what details matter is often subjective. I've looked around my desk and surely the vast majority of the objects here use the simpler rounded corner but I really fail to see how it's bad craftsmanship. If anything I'd argue that for professional appliances the circular corners convey a less organic, more industrial look that feels, to me, more suitable. But then again, I enjoy brutalist architecture, so you can probably safely discard my opinion.
