Yeah I think the lighter spider is enchi.
This particular white mystery one does not have enough color in the face to even see that eye striping, but at least some color in the body is developing. Probably CG champagne pastel. The similar ones with brighter orange may have enchi and that is what's causing the extra oomph to the color. If they develop the tiniest bit of grey in the head or dorsal, I'd rule CG out.
