Granted, but that close pass around the Sun was also the most barren, videogame-like rendering of the Sun ever. A textured sphere with a few geometry-based prominences. No particle effects at all. When was TOS-R, late '90s? Now take a look at the Sun renderings in the 1998
Lost In Space movie.
Heck, even the aerobraking maneuver at Jupiter for
2010: The Year We Make Contact (1984) was more dramatic, and that was done with practical effects. (There were later shots of
Leonov in orbit with a CGI cloud pattern for Jupiter.)
