Yes you should always extrapolate, if you make a pathtraced offline rendering model you can be lazier but in realtime and in general if you want it to look good you need to add more artistic touch and think how the surfaces would be worn off based on physical logic and define those out more. On a screen and in varied…

Do you mean I should add some noticable wear on all the large curves? I try to go off my references and most of them are pretty clean so I can't think of any examples. I…
