Hmm, I guess it doesn’t technically need a dual axis to lift the leading edge, I just don’t see how you get the final bit of rotation given that when you look at the pictures (AI enhanced mind you) the hinge arm (yellow) is maybe 75-80 degrees rotated from its resting place on the first element, yet the wing is more like 120 degrees rotated from its normal position.

I think I see the confusion. If you look at the area where the bell crank is attached to the rear-wing endplate, the lower blue dot is not the hinge point. Rather,
the hinge-point is very close to the point of that yellow mark you have made. The rotational axis of the wing lies about 2/3 the way between the fixed first element trailing edge and the top edge of the rear wing endplate.
This is a similar hinge location to the rear wing that Audi first showed up to preseason testing with. The addition of a bell crank enables the vertical displacement that Red Bull has achieved here along with the extra rotation powered by the dual articulating actuator arms.
I see the same, and described the same earlier in thread, with bell crank arrangement too. Those two "actuator" looking component could be passive assistance "rams" that work by going over centre to help movement and give positional stability at each end of travel.
There's very simple illustration of this in normal saloon car trunk lid hinge arrangement, sitting at each side of lid with simple gassed passive strut in folding that panel up and away from its closed position on a notionally displaced centre of rotation (very close to this panel sweep) that to fold the panel in a manner that travels toward inversion (gets the lid out of the way) back over the car rear window.
Audi are routinely good at this too, there's a very good example just outside my house
