Streaking gets worse with lower exposure

You know what I find interesting is that in your new ISO100 NEF, the streaking seems to be more apparent next to the bottom half of the window, where there is less light coming through.  Perhaps the streaking is not a consequence of the bright areas, but of the dark ones.

Here are two exposures, 1EV apart, shot at both ISO 100 and 200. The lower exposure is much worse, indicating it is something with the shadow+channel balancing/black clipping for rows which also have saturated pixels

Base Exposure, ISO 100

-1EV Exposure, ISO 100

Base Exposure, ISO 200

-1EV Exposure, ISO 200
