There was this thread as well but they don’t respond to requests for the captures. https://originaltrilogy.com/topic/Star-Wars-Laserdisc-Preservations-See-1st-Post-for-Updates/id/15283/page/1
I can’t remember if I ever asked them directly I want to be completely fair, I asked in the thread for the Japan laserdiscs. Never sent a pm. It was easier for me to just purchase the discs and watch them on my old tv set.
