2 door front doors are the same as the traveller whereas the 4 door front doors match the van and pick up.
The B pillar has to be shaped for hinges for the back doors on the 4 door and is also deeper front to back, which is why 4 doors can have a higher seat belt mounting point than the two doors which have a much thinner B pillar. (Travellers can too but they have a completely different B pillar to allow for fixing the wood to.)
There is a seam on the rear 3/4 panel, seen from inside the boot but not obvious from outside.
So when you say "are the body pressings different" I think it is more a question of which ones are different. I think most of them are the same.
It may well be that it is the B pillar and the C pillar only, then the doors and sill areas. With the two door having a welded on C pillar/side panel.
