Okay, retyping this to make it shorter.
The DC is touring arthouses as part of the science on screen series. FC bookings are digital but DC ones are 35mm.
Do yourself a favor if you're nearby. GO!

I saw a packed midnight show resulting in the best version I've ever seen. Besting even the 35mm FC in 2008. Gorgeous, organic and natural with perfect grain and fine detail which revealed an even more delicate color palette with some of the more vivid look found in the old IC transfers.
I could easily pick out things like the wires or Rachael's fluctuating back in the office. Blacks were pitch and deep, for example after Deck wakes up from his dream you cannot see anything besides the vague shapes of the piano.
Remember that the DC was hastily made from a dupe of the US theatrical neg after having to abandon the more grand vision of Ridley making a new cut. Thus the violent bits are gone. But since the film hadn't been reprinted and was only 10 years old at the time the elements were near pristine and the printing process had only gotten better.
I don't think there is a better element around. Who knows how the original was timed or printed and if it was even accurate. Comparison would help, but I can sincerely say I have never felt the film more accurately presented. Sound was optical Dolby surround, very clean and I even picked out backing score in the mono surround.
Funnily enough the hasty process is revealed in the ending. Once the doors close there is a moment of black screen and silence before the end credits come up with music. And the alignment is slightly off kilter. ;)
My two cents:
Re-transfer the DC @ 4K.
Incorporate the violent shots from the IC and color time to match.
Additionally the original narrated audio and happy ending could be seamlessly branched for those who prefer them.
The only fixes from the FC I really find desirable are the continuity ones, i.e. the end dove shot, spinner wires, lip dialogue in Abdul's shop etc. If desired these could be implemented into a sort of Purist Director's Final Cut, because we are literally that nuts for BR.
