Well the movies can not be Touched without the involvement of the Original creators. So the new Color Grade has to be approved by the director. The OGs are responsible for what you see now, so it's Canon as far as creative intent.
In terms of theater release, obviously it won't be the same because Theaters have very low contrast ~500:1, An IPS Tv has ~1000:1 contrast, a VA TV has ~3000-7000:1 contrast.
For the 4K releases, they're all color graded on OLEDs or LMCL, which means an OLED would be the most authentic way to watch them. LMCL is not affordable for the general public. VA is the budget solution. IPS is NOT suitable for movie watching unless it's LMCL IPS, 31 inch, $40,000.
