Working with the 16mm ESB, I can say that it is very difficult to color time that beast. First, there aren't any scenes that are both "normal" and "complete", meaning that they both take place in normal lighting and feature a broad spectrum of colors. So you can set color that looks great in one scene then it turns out to look terrible in others. Also, while the DVDs are of course way, WAY too blue, the GOUT may not be too accurate either... I was surprised by how blue the snow looks on the 16mm. Ultimately, ESB color timing is going to come down to the preference(s) of whomever is doing their own edit, taking into account a variety of sources. Hopefully PSB will be done in time to serve as yet another reference, however questionable.
