Yes, but Bandai seems to have gotten the whole concept backwards---the ships are intentionally "over-saturated" in real life, because so much of it is lost on-screen. If you're going for "actual studio model under normal lighting" the kit is too colorful, and if you're going for "on-screen" then it's WAY too colorful.
I too have never seen any good "original 1979 paint job" pics. I don't think they exist, or they'd have shown up on the numerous "how to paint the Enterprise" threads on the 'net.
(side note, IIRC, the Ent-D suffers from "double" de-saturation----the one that naturally occurs from filming, and the one the studio does because the first time they filmed it they thought it was supposed to be a grey ship, not a blueish one, and so they took out all the blue----but they couldn't go and NOT do it for all the rest of the episodes once they heard back from the original modelers/painters, so they had to keep doing it, thus a grey Ent-D). (kind of like the infamous green skin paint tests, if you know that story)
