When I called Coastal the rep said their CI-4 grade Fleet 15w40 had approximately 1200 ppm phosphorus, 1410 ppm zinc, and 2400 ppm calcium. Unfortunately, I forgot to ask how old the specs were.
I suspect those specs may be from when it received API CI-4 certification and thus may be a little of date.
Also, it never appeared dark to me out of the bottle, same color as any other motor oil.
