It seems to be from the Guitar Rig 6 Pro components. It's misleading to put that image unless you are really getting that GUI these days. If that was the case, I would have got it as part of the NI updates.
Or maybe that refreshed GUI will be coming to the standalone (VST/AU) plugin version soon, along with other Solid Mix series effect plugins.
Noticed a funny thing on that page though. The audio demos linked are of Passive EQ and not VC 160.
