Wow! Way more CA with the RIV. I don't understand why, but the a9 image is clearly superior.

I don't know, but a theory: if the lens throws equal CA in both cases it will show up more on the RIV. Say there's half a pixel width of CA on the A9- on the RIV that same aberration would be about .8 pixel width, so it would show up more clearly?

The RIV image started darker, LR brightened it up more.

Interesting. Maybe you should do the conversion with no adjustments at all.
