No, I have these 97 tapes with the "making of SE" featurettes and I remember them very well, because I used to watch them all the time as a kid. They did speak about fixing the matte lines on the snowspeeders. But they only spoke about the matte lines on the Rancor to show and explain what the matte lines were, because they were so clearly visible in those shots.
I grew up on those tapes! Those little introductory featurettes are part of the movies for me. I never watched the SE in theatres either. My only experience with the OT growing up were those SE VHSs.
When I bought the DVDs it was so jarring to watch the movies without those featurettes in front and without that big booming voice saying "Sit back and enjoy George Lucas' definitive version of _________: Special Edition"
I remember the ESB featurette highlighting the Hoth speeder mattes and transparencies.
