In the blue circle I can't see any difference, in the green maybe it's a matter of distance/angle of the picture.
On the contrary I see a difference in the diffuser where it joins the rear impact structure; the new one seems to have just one "lip", the old two (here too, not sure, maybe only perspective).
OK the minor height (and length?) of the vanes of the diffuser (reduced as for 2021 regulations, I think).
The cooling exit were already that way, maybe never before they had been captured in a so favourable angle.
Anyway, now Ferrari is starting to change in a significant way.
My "fear" is that now they are building an aero that works related to the little power of this year engine and that will not suit next year more powerful one.
