I don't like the bare metal look either. It says like mad max, cyber punk, being called 'bombadier' with bombs on it, even 'wartime' or 'post apocalyptic'. I think above anon is right that the bare welds are ugly but I think that's the deliberate look, it's supposed to look 'hardcore'.
I think that aesthetic is at odds with the nature of a new steel road bike. They are expensive and comparatively non-functional. They are form over function. Which is honestly not even a bad thing with a bicycle, bicycles are aesthetic items. But that aesthetic says function over form. It is disingenuous.
