There are at least 3 versions of the ESB out. The original Grindhouse, a DCP cut, and the ESB deconstructed. Along with color corrected versions.
People are free to correct, and use those for their own projects.
The final cleaned version, will be based on a Fuji print, that has much better color quality and minimal damage to the print.
It will be awhile before we get around to releasing that.
