This can also be found in the new color matching thread I created, but I guess it is also relevant here. I wrote a script for matching the colors between two sources very accurately. Since the colors of the video samples for the LPP preservation still need to be adjusted, I thought I would do a few tests. I have matched frame 8228 for the LPP preservation to four sources: GOUT, GKar, 35 mm scan from a different print, and Harmy's Despecialized Edition.
Here are the before after comparisons:

The colors match very well. However, the color corrected LPP framelooks faded. There is not much detail. In some ways the LPP scan is comparable to the GOUT and GKar. This can have three reasons I think:
1) The diference in quality is due to compression
2) The quality of the scan is not that good
3) The print itself is in pretty poor shape
Personally I think the compression is the culprit, but perhaps -1 could provide the uncompressed frame 8228 to be sure...
