I'll give it a try.
In my opinion you are seeing primarily MC. I would say Red shifted left and up for about a pixel. It can be non-uniform across the image if the panel is also rotated slightly. I also believe ther is a slight mis-convergence between the Grn and Blue as well.
CA is a subtler artifact that is wavelength dependent, occurring because each light wavelength bends differently as it passes through different mediums (diffraction) and would be most apparent at extremes of lens shift and outer portions of the frame.
In the colour bars pix the differences in the transitions is likely caused by the RED channel being OFF (well at least as well as LCD can be OFF
). For example in Image 9: In the Cyan and Green bars, Red should be effectively OFF which would mean that it would not introduce and colour fringing whereby in the Magenta to Green transition it would be affecting the Green. I also believe that one of the other channel is sub-pixel shifted as well, since the Green to Cyan transition is also slightly blended.
With image 11 (Blue to Red) the Green channel should be effectively OFF which would account for the black line as there is no Red (it is shifted) or Green (it is OFF) or Blue (it is one pixel away from the Red).
I also believe you've got some sharpening artifacts which are particularly apparent in Image 3 and Image 12. I've SHARPENING turned OFF for all my sources yet my 700 still exhibits some of this type of processing.
So for what its worth, those are my impressions. I'm quite willing to change them at a moments notice should someone point out the errors in my thinking.
