Jetrell, may you check your three different DVD editions, and see if there are some color differences? I wonder if the older one has a color grading like the PAL LD, as some seems to claim.
Many of you remember that my main color matching script, despite the fact it produces wonderful results color wise, has some problems in the clipped whites, producing nasty artefacts; today *it seems* I have fixed somehow that problem... can't be 100% sure unless I'll encode a complete movie - with this brand new wonderful script, and my fast NASA-like computer (yep, like a 1969 NASA one, more or less), it will take just a tad more than a week to encode it - but, according to several screenshots I focused on, the artefacts seems gone or they are so greatly reduced that is impossible to notice them - at least, that's what I hope.
To stay true to the spirit, to the look & feel of the PAL LD, I decided to leave some of the clipped whites untouched; yes, it is possible to fix them further, using BD luma, but doing so will alter the color balance of this result, that seems nearly perfect to me.
Here you are an example of the latest color matching: 🔍http://screenshotcomparison.com/comparison/199684
Note: for the ones worried about the clipped whites, they are noticeable just in few shots. like the last one in the previous comparison, when there is a great explosion, on sometimes in the very hearth of the brightest flame; as I have watched the whole movie as LD capture just yesterday (and the fact the regraded version is something like I think about 95% close to it, and up, but with clipped whites partially fixed), I can tell they are not so distracting in motion, because last for few frames (explosions) or are very tiny (flame hearts), and don't occur in all of them, and with the same intensity; as you can see in the next image, in the regraded version the clipped whites are partially recovered, as in many shots apart few ones - top LD, middle BD, bottom BD regraded:

EDIT: actually there are some explosion shots on Blu-ray with severe clipped whites; these are unrecoverable and, eventually, should be replaced with footage from LD, or older DVD not affected by the problem.
