Looks a lot like your color balanced reel 1 of the LPP. That’s nice !
However, the blown out whites of the blu-ray remain in your attempt whereas Neverar resolved the problem in his work. So, I was interested about testing something : manually adjusting the curves of Neverar’s picture to approximately match yours, except for the far high color values. Here’s the (not perfect) result : http://screenshotcomparison.com/comparison/196918/picture:0 (compared to your last result and Neverar’s version).
Anyway, the question of the distinctive look of Tatooine’s scenes is still here and Neverar’s final result is probably the one that is the most correct.
