I’m not sure 97SE was ever shown in HD, but you’re right the 04SE was and that should be the highest quality version that I’m sure someone has on a hard drive somewhere.
Well, no, the broadcasts of the ‘97 version wouldn’t have been HD per se, but IIRC there were captures done of digital broadcasts in 16:9, letterboxed in 2.35:1, and these may or may not look better than the best laserdisc preservations out there.
But yeah, I didn’t see anything in the indexes about a simple hd broadcast preservation of the 2004 version.
