I think the added depth in the set is very subtly done. It's isn't 'clearly' deeper.

You have to really strain to spot the difference and that's with the two set photos next to each other and who's to say than Han didn't extend the cockpit between the two films?

I prefer the un-cropped versions they have rich and compelling detail to them which is absent in the cropped versions.

I do hope Ady will be as OCD when it comes to making the Executor bridge in ROTJ look as good as the one in ESB (what is it with 80's sequels and buggering up hand-me-down sets?).
