I don’t know of any. Dre is working on a ROTJ colour correction but it’s not done. Adywan has done one for ROTJ Revisited but I don’t think it’s been released. Your best bet is probably the new Disney 4K releases, which have a more natural colour grading. Unfortunately they’re currently exclusive to Disney+ and therefore only available at all in the US and Canada. Hopefully we’ll get them on discs by mid-2020.
