I notied that even with BC models, that they'll appear excessivly bright and garish in a model previewer or while editing, but either soft or dim in game. since I only have the various trek movies on videotape, rather than DVD, I've never been able to look myself. what I saw, personally, is a color I call "Ink Blue", the color of standard ball point pen inks, here (a blue-black). it's kinda like trying to determine the exact colour of ambassador ships and X wing graphics in the star wars universe.
I'd try altering the color-temperature of the image till it looks right again. when scanning in graphics and images, people complain constantly that their colors get burnt out, or bleached, etc. I always adjust the color temperature to get a more realistic color. nobody seems to know how to adjust settings

there's an extensive discussion on here, somewhere, involving the true color of the original enterprise. it mentions the "color Bias" of the particular film that was used needs to be compensated for.
