As far as I can tell, Ferrari's design is now basically right between McLaren and Red Bull in terms of size and the ratio between vertical wall "direct" outwash and horizontal bottom surface "pressurisation" outwash. In my view, they won't have a lot of room to improve this design by the end of the year without massive internal redesign which would increase the cost a lot. They might just focus on further floor evolution, especially concerning edge wing treatment, and potentially an update on front wing if it can yield a cost-efficient improvement.
Here's also formu1a.uno comparison of the floor inlet, outboard leading edge height decrease is quite clear. We can also see that the whole tunnel roof surface is starting to compress much more now and it's visible from the junction between fences and the roof, explaining the raw performance increase that caused the bouncing. Proper setup will alleviate this issue
