I'm struggling to see it, I'm afraid. Those pictures don't really demonstrate that they are the same. Actually looking at the lower wishbone mount it seems quite different due to the differing noses. You can't tell for certain, but for me the Force India has it mounted higher.
I can't tell if they are running the same camber, but it wouldn't surprise me as they are both on the same tyres.
They are broadly similar, like all F1 cars:
