Did you capture lossless in YUV or RGB? The sample you posted was AVC reencoded, so that was YUV (YV12) but this doesn't tell how it was captured. If your capture (the .avi) got converted from YUV (S-Video) to RGB it is possible that you got out-of-gamut values which are irrecoverably lost.

The NTSC_M_J after decreasing "color boost" looks fine to me. No clipping, that's essential.
I don't use DaVinci but it looks like "color boost" tweaks the contrast and saturation (in avisynth terminology), very similar to what I suggested with my script.
You can judge yourself whether the black background of the intro is "black enough" or still a bit grayish.

Can you sharpen the chroma in DaVinci? The edges would look sharper with less color smear.
