I liked how the shiny white bridge screamed "NEW!", and it worked well for the finale of STIV (as did the same colour schemes on Voyager's USS Prometheus and the reimagined USS Enterprise in the last movie) but I can't see the bright shiny look working in STVI, where the Enterprise is (suddenly and inexplicably) supposed to be old, obsolete and heading for retirement along with the crew.
I've seen photos of the Star Trek Phase II
bridge (the real Phase II, not the fan film series) with the white walls and shiny trims. It seems that look was originally meant for the aborted second TV series before the sets were repainted in grey for TMP.
