Unfortunately there is no way to bring all colors back since the GOUT is sourced from a faded interpositive.

Technically, yes. But practically speaking, if you know for what you're aiming, mild fading shouldn't present much of a problem, as demonstrated in this more severe (?) fade before-and-after:

Well yeah, some fade can be corrected if working from a raw scan with all the color information intact. The GOUT has unfortunately been desaturated even after the scanning. In lots of scenes there are parts of the picture which actually has no color information left at all. Here's an example:

Here the saturation is set to 100 in photoshop. Check the left part of the back wall, or the ball-thing in the middle of the table. There simply is no chroma at all in those parts!

So while I was wrong saying the reason is that it's from a faded interpositive, (well that's partly true) I'm not wrong saying it's been treated very badly after the scanning.

EDIT:

Here's the same part from the 70mm scan, with same saturation setting in photoshop, so you can see how much more color and balance there is in the original:
