I like that un-used matte shot. It fits the asthetic of TMP, in that it's kinda different to anything we see anywhere else in Star Trek. I wish they'd been able to use it.
The shots that they used in the Director's Edition are terrible. It was just an exercise in trying to make it all look like certain similar shots from later movies and tv shows, rather than it being a case of the original film-makers intentions actually being honored. It was revisionism of the worst kind.
