I'm not sure the -400 had the same wing design as the early -100s and -200s. It was certainly a lot more clever, being 20+ years later...

The -400 had a slightly extended wingspan and winglets, as well as blended wing root fairings, but it still shared the same basic geometry as the 'Classics'. Externally the wings were identical up to the point where the extensions were added, including the change of wing rake I refer to here. There are lots of photographs of -100 and -200 wings that show the same 'kink', but not quite as effectively as in this photograph.
Here is a drawing of the 'Classic' wing in plan view
