It's not all about looks you know. Newer DX versions allow to do things easier, also DICE specially said that DX11 allowed them to do such things that are crap in DX9. DX9 cannot do AA with deferred lighting as well unless they support lower quality post AA. Also DX10/11 are better at geometry instancing and better optimised.
