It seems that the pre-4K BD color grading is similar to old DVD (and maybe HDTV):
Yes, the old pre-4K BD is probably sourced from the same master as the 2005 DVD. However the 1999 DVD uses a different source from both the pre-4K BD and 2005 DVD - you can see this if you compare the contrast differences. The HDTV in on the other hand is sourced from the same source from the 1999 DVD transfer, but there have been other HDTV sources which are sourced from the 2005 master as well - really depends on which HDTV version you have.
The 4K BD is a happy compromise of the 1999 and 2005 in my opinion, but for those of us who are used to a more muddy transfer over the years such as the 1999 DVD, the 4K BD seems a little bit too 'vibrant' in parts.
