The DX11 client is only an additional 20MB or so. It still uses the same assets as the DX9 client, which makes up the majority of the size of the game's installed files, so there shouldn't be much variation between the PC and console clients.

I imagine the difference may be related to the data compression methods used. I wouldn't be surprised if PS3 and PS4 use a completely different compression method to the PC for their patches, resulting in smaller downloads but unpacking to the same file size. I wouldn't worry about it too much.
