Actually, looking at both the R2 shots, they both have the same level of detail but the ED2 has altered the black levels (just check the "eye" dome on R2's head and 3P0's stomach and you can see the the loss of details due to black crushing). Adjusting the levels have just made the dirt look more prominent, but they are both from the same source. Check out the left side of the picture and you can see the edge of the frame is faded in both shots in the same place. You can also see that a sharpening filter has been applied to the ED2 by the white edges of the top matte bar. Very common by-product when using a sharpening filter. And the shot of R2 in your first post shows the bad aliasing that is apparent in the GOUT but never seemed to be a problem in any of the laserdisc preservations i have.
