Ferrari are now back to their original outwash generation with a vertical wall, but even more moderate than SF-23 A-spec. By pulling the whole sidepod inlet to the back, they've allowed the car to require less pressurisation to provide the flow management they need to keep the rear end clear of massive front wheel turbulence
By adding a horizontal wing-like surface above, they are now adding interference phenomena to this design (unlike F1-75 and SF-23A) and this will increase both the pressurisation at the front and suction to the rear. The area around the curvature under the Shell logo is particularly interesting. Here, flow will accelerate under the influence of both the bottom and side undercut surfaces, which will increase the local suction peak due to positive interference
As both these surface are forward-facing, this suction peak means Ferrari are generating some amount of thrust in this small local area. This is a known phenomena and it's used for overall drag reduction when executed properly. This area around the VistaJet logo will probably evolve with the next upgrade package and I'd bet it will be replaced by a more streamlined surface like the rest of the grid
