The pink is built into the master for the LD. In fact its not uncommon to see a pink tint on older telecine masters from the late 80s and into the 90s. Much like its not uncommon to see green in HD masters today.
I definitely see green in the BD master. Anytime there is white it tends to be green, subtract enough on that green and you get close to the same level of pink of the LD master.
