Comment (by cehoyos):

 Replying to [comment:2 ErikCJohansson]:
 > Looking at the histograms, you can see the shift in the higher range,
 but seems ok in the lower range. I will attach histogram plots of the
 source image as well as your two samples.

 How can I see in the histogram plots that frame 1 has a higher magenta
 colour shift than frame 0?
