I have a theory that the venturis under the RBR have a more rearward COP and have bigger volume underneath. Posted in w14 thread. And i think this is why they can ride lower.
It's not really a theory, it's a well discussed fact during last year. The profile of RB18 and now AMR23 (by the looks of it) provides a small and powerful low-pressure zone in the rear and somewhat limits the potential for more downforce on its own. The profile, not the floor. One of the reasons Ferrari had more floor downforce than RB18 until TD39 kicked in and the car was raised forcibly.

This is very far from what typical ground effect floor pressure distribution looks like and the rear end is practically the same as previous generation diffuser floors. You can be sure that other teams, with conventional ground effect floor design, have a very, very different pressure distribution, far more even as opposed to RB peaky downforce design.
The one thing that became clearer now with more pictures is that there is actually a (very) short surface of the throat, but it did look like an edge last year. Doesn't change the philosophy, just the pressure distribution a bit...
