Agreed. As a tech artist, I'm 100% positive I could get a bang-on reproduction using Arnold or some other really solid photorealistic rendering engine, but it would probably take longer than using real cameras, practical props, and doing a bit of massaging in post. The modeling, color, camera angle/focus length/etc. are all really easy. Tweaking the subtleties in the light, glass shaders, fog, etc to get them good would take quite some time. It would only make sense if it needed to be animated or you needed a bunch of versions with modifications. Definitely a 'use the right tool for the job' kind of thing.
