No, I do not think that the color issue is caused by the broken fields.
I have no clue what to change, since I can not reproduce the issue. For me the colors do not change.
Looking at the histogram one can see that the luma range is limited range (16-235).
What did you use to compare the colors?
Do the colors differ if you open Hybrid two times and look at the reencode and the original (overwrite scantype to progressive) in Vapoursynth Preview windows?
(atm. my guess is that whatever you used to compare the colors is doing something wrong. On Windows I would guess this might be an overlay issue,..)

Ps.: The Vapoursynth Preview also has a color picker, to see rgb colors,..
