Adding to Joseff comments, the same thing with the rear wing (most notably on the Toyota & Williams')
I was wondering if they are using a bit of "divergent duct" theory here (decrease speed & increase pressure) to create a greater pressure differential between the surfaces of the wing?
Also if there was a bit of downwash from the wing(s) & camera ontop on the air intake requiring an alteration to the AoA?
If anyone had a CFD graphic, tat would be great.
Cheers.
