I've heard rumors that some move archival enthusiasts have developed Laserdisc capture hardware which samples RF directly off the laser pickup, for theoretically-ideal capture quality. Anyone know if there's any truth to that, and how to get in touch with such a person if so?

It's not a matter of results being *visibly* better. It's that if a player has a good/no-good signal from the pickup for any given sample read off the disc, the data can be *provably good*, and a known-to-be-perfect dump can be merged from reads off multiple discs.
By way of analogy: Your argument is that a dump of a bit-rotted graphics ROM IC from an arcade board is just as good as a non-bit-rotted dump, if the affected bits don't visibly affect the graphics shown in-game. I won't sugar-coat it, that's not preservation, that's half-assing.

Not only that, capturing the visible video with a capture card doesn't capture the data contained in the vertical blanking region, where many LD arcade titles store data used by the games. Even worse, the digital data stored in some audio tracks can get mangled.

This is the most important part. The frame number and other data stored in the VBL is absolutely critical to operation; without it you just have a weird, disjointed movie.

No, that isn't even similar to my argument about LD.

The ONLY think of interest on the disc that doesn't come out the video and audio connectors of a normal LD players is the frame counter. Sure, you may be able to recover bad sections by splicing captures of multiple discs.
