Don't overthink this- LOL
DexCool is not recommended for Porsche on their website. Only GM, Saab, VW.
ZEREXâ„¢ G-40 is suggested for Mercedes-Benz, Audi, VW, Porsche, others
So, yea, you need to overthink this because you're posting bad information. LOL

I'm not sure if I would trust Valvoline's guide, or some of the other supplier guides. They tend to say Purple coolant comes on VW from 2006. My 2008 VW and 2016 VW, both assembled in Germany, disagrees, has they have been pink.
VW's G12+ coolant for instance is Pink, but is neither a P-HOAT or Si-HOAT.
But, there is a G12++ that is a Si-HOAT and it's pink still.
And there is G13 that is also pink, and uses glycerin and Si-HOAT.
