I assume you got that other pic of the three US versions from me. Those were taken obviously from an inferior LD player, as the level of detail and ghosting suggests. Also keep in mind that things like color and hue will vary between captures especially when different equipment and software is used. I have a feeling that if I had captured a shot of the Japanese DefCol LD and included it, it would look very similar to the US version with only the IRE difference apparent. Also note that the hue is different between the US DefCol and the US Faces, with the DefCol actually looking closer to the red/purple hue of your Japanese capture.
So I guess what I'm saying is that the hue might not be as far off as you think. I just depends on your capturing equipment and laserdisc player.
Oh, and by the way, that capture is outstanding! Very clean and detailed. May I ask what laserdisc player you used?
