My original D7100 shots above were 14-bit lossy. Here are converted raws from 14-bit lossless, this time at both ISO 100 and 400. I don't see it at ISO 400.

I think I can see it in both shots Adam, but only just in the second shot.

Horshack, you changed exposure (1/320 vs 1/1250), that would make the ISO 400 image noisier, and the streaking could get lost in the dithering.  I can just barely see some horizontal banding in the ISO 400 image against the texture of the wall, but I am not sure it is aligned with the blinds.

ISO 100 pushed 5 stops (left), ISO 200 pushed 4 stops (right)

No perceivable streaking there, with more light (1/200).
