I am curious as to the paint scheme. It appears the drawing of the model on the website is inaccurate. I can not find any roster shots of the two road #'s with the "We will deliver" on the side of the long nose like BLI is portraying.
Do you just mean that the road number is not matching the paint scheme? I assume you mean the slogan on the long hood, like this:

Edit- So you got my curiosity up. Not that I enjoy researching the mother ship but.....
It is odd that both 3056 and 3079 are listed on at least two UP rosters I looked at as SD40s not SD40-2.
Quoted directly from Utah Rails site:
3056 - Oct 1966 32408 15 May 1990 Leased to NdeM in November 1989 to May 1990; sold to Morrison Knudsen in May 1990, rebuilt to SD40-2 by Morrison Knudsen, Boise, Idaho, completed as CSXT 8470 on 30 August 1990.
3079 - Dec 1966 32431 8 Oct 1992 Leased to NdeM in November 1989 to November 1990; returned to UP and stored; leased to NdeM in October 1991 to October 1992; sold to National Railway Equipment in August 1993; sold to Morrison Knudsen in January 1994; rebuilt to SD40M-2 by MK Rail, Mountaintop, Pa., completed as SP 8686 on 21 December 1994 (assigned UP number 4712).
Another roster lists 3079 as being a former CNW SD40-2 unit #6916. Seems like this might have been a renumber after the original 3079 was sold as above (maybe?). ??? note the date on the photos below are after the locos have been sold.... Adds to the theory of two sets of locos with the same number.
Here is 3079 with that paint scheme

And 3056 ...

So I guess it depends if you really care if it is really an SD40 or and SD40-2 (seems to be a bigger prototypical issue than the paint scheme), as both the road numbers appear with that slogan. That, to me, means that the 3079 would be a better bet at prototypically correct depending the exact date you are modeling.
