FWIW, I feel that Sanjuro’s grade is reminiscent of the flushed hues of the THX home video remasters. A lot of people like that look (either due to a true preference or simply a positive association with the most common home video releases) and may consider the target look to be somewhere in that neighborhood.

DrDre’s reminds me more of the pre-THX look, which is presumably more closely aligned to the 35mm sources. Given DrDre’s method’s though, his personal “target” look likely isn’t nearly as relevant as what the colors simply are like in the source. 95% of the color is just what the math says it should be, 5% is finesse. Not that the 5% isn’t critical, but it’s the difference between two slightly different yellowish hues, not the difference between red and yellow.
