    Yes, it is. You can control it.

    After creating dialog:

    WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();  
lp.dimAmount = 0.0f; // Dim level. 0.0 - no dim, 1.0 - completely opaque
dialog.getWindow().setAttributes(lp);

    Upd: you can even add blur behind the dialog:

    dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

    Upd2: Blurring is deprecated since API14:

    This constant was deprecated in API level 14.
    Blurring is no longer supported.
