Here is a comparison. I actually dialled back the orange a bit:
The CG FX tweaks on the final cut of that landing shot are less obvious in a still, than in motion. Re-watch it now and you'll see what they did.
maybe you did that to make the sky orange so it wasn't blue (at 16:25)? Because that is a continuity error they should have fixed in the Final Cut (orange/blue/orange sky) and the sky is consistent in this edit.
That's a slightly more complicated question, as it was not a final cut change.
In 2006 a new "Digitally Remastered" DVD of the Director's Cut was released (which is also the version you'll find on all blu-rays of the DC). It made a number of changes to the grade, from what was last seen on the old un-remastered 1999 DVD. Such as introducing inconsistent blue skies to some shots in the sequence you are talking about, blue and/or green shots in the opening "hellscape" sequence and making some scenes like the noddle bar aggressively teal. Many scenes feature more or less the same grade though.
A year later when the final cut came out, it was based on that new 2006 transfer, so ported over all those grade changes, plus made more changes to everything else.
Here is a comparison:
The original sequence had a consistently golden glow, as if the sun was going down, which I tried to restore to the HD footage:
