Hi,
the 1993 german Star Wars Laserdisc release also known as "SilverScreen" Edition seems to be very similar to the french Pyramid Editions. It is quite possible these come from the same master.
I am talking about these:

These Laserdiscs are definitaly DVNR-free and don't seem to suffer from white clipping or crushed blacks as much as the 1995 THX versions.
However the transfer is really noisy, has washed out colors and some missing frames. It has about 352 lines of vertical resolution and was released around same time as the french Laserdiscs.
I am planing to capture these Laserdiscs for preservation and release DVDs and/or MKVs but I am still in an early phase testing and trying a few things.
