Sounds like the person you spoke with @ Valvoline was misinformed, or had incorrectly synthesized that information out of something they were told. G-05 is virtually identical to Motorcraft Gold.. that, or it IS MC Gold.. and, as the MSDS sheets show, essentially the same thing as Mopar pink. Perhaps the Valvoline person was informed that G-05 is the same as Mopar Pink, and that is what replaced Mopar Orange?
As far as the dipstick idea goes - I don't really need that.. I can see the coolant in the resevoir, but it's not obvious at casual glance - In order to do it easily, I have to hold a flashlight up to the side of the resevoir and look carefully... it's tough during the day. The Mopar Pink (or if I decide to, Rotella ELC or Peak Global) would make it VERY obvious at a glance.
