Here's a screenshot from WookieGroomers GOUT vs DVD:
No original shot, and the red lighting on that Stormtrooper wouldn't be there if that was an actor being blue screened. There very well may have been a physical hanger model, but everything else in this shot is 100% CGI.
Any chance of getting a scan of the picture out of the book? Be nice to have around as a OT.com "Fail" picture.
