It seems that the pre-4K BD color grading is similar to old DVD (and maybe HDTV):
Yes, and that (2nd) DVD was widely criticized for being way too bright and blowing the highlights out. The first bluray just recycles that transfer. The 4k bluray definitely has the best colors of any home media release so far. (The first dvd is murky and pink and the 2nd DVD/1st Bluray is way too bright.)
