I got a test sheet of PaintON and agree with all your findings: not watercolor paper, suitable for pen and ink, and so on.
I then bought PaintON Lisse, the even smoother variant. To my surprise, it was more yellow :-( and better than PaintON (your tested version) for watercolor. But still no real watercolor paper.
