ONLY? ...That's like comparing windows movie maker to adobe premiere pro or sony vegas!
Regardless this trailer , textures are basic , lighting is very basic ( 2 keylights and 2 front light), all props are basic too , the huge difference with iclone is animation (characters , camera ,motion blur).
Because I don't share my iclone work for know, What I can do today is visually amazing...
As you said for texture , you can't bypass diffuse , specularity, Ambient occlusion for good result.
But I know that sourcefilmaker could do looot more
