I won’t buy it either, the current Blu is sufficient enough. The yellowness in not that big a problem, it even looks good in many scenes, and I turn down the colors a little bit, and then it’s fine.
I also prefer the long version (minus grotto), and love some of the new scenes, and would never watch the film again without them.
Still it’s already a masterpiece, and all in all the same masterpiece, in the 161 min version, and it was already one on my old fullscreen VHS in Shitoscope with colors not worth mentioning. And everything I watched since is miles better than that old tape.
