From the discussion here it looks more like small problem in analogue domain. Maybe some samples of NEFs 14-bit lossless can help to understand better - the links to those posted earlier already expired.

I think one D5200 sample is still available here (_DSC0066.NEF):

while the best Horshack's samples were not NEFs:

But considering the D300s sample:

question is whether this is in fact special to the D7100/D5200, or occurs with other wide-DR sensors too, if one looks hard enough or finds the right test conditions.

Iliah, thanks for joining in.

_sem_, Andrea Dawn's sunset rock shot (dsc0066.nef) is probably not a good candidate for this discussion.  There is a sun-aligned lightening of the shadowed rocks on the left, but it appears to be part of a constellation of sun rays and possibly a lens flare. I count at least 13 rays at all angles. The line artifacts seen there appear to be nothing more than regular deep shadow banding.
