The extra damage in TSFS falls well within the realm of dramatic licence, IMO. If you look too closely, Trek's continuity doesn't hold up at all. Whether it's those damage control graphics actually being for the original series version of the Enterprise (and showing damage to crew quarters and not engineering systems), or the Enterprise shield graphic showing the Phase II version of the ship, , Khan turning white between SS and WoK and his followers morphing into Aryan youths, Saavik being recast and looking and acting completely different, or Khan wearing a current uniform insignia which supposedly belonged to Marla 15 years ago, the Reliant somehow mis-counting planets... what's a bit of spaceship battle scarring next to all that?

Agree.
