The top image is from the 1992 US Pan&Scan Laserdisc, showing little to no scan lines on Vader's hologram, while the 1993 version has fat scan lines and the 2004 version has smaller scan lines.
Your description of this one is wrong, the top image is a 8mm-cap (the source is probably the 70mm cut) showing the "unfinished" hologram and it seems to match the '04 DVD holo pretty close. All other versions (probably final version) have the scanlines as seen in the middle pic. It's all a little messy cause the Special Editions also have a mix of "final" and "unfinished" versions of the holograms and screens like the GOUT of EMPIRE. Either it was never set in stone how they should look or they didn't bother to composite the scanlines or they simply forgot it, like they did with several other composites.
