It's more that your settings are the same for the whole film, so where the colour changes between shots differently in the SE than in the original, yours follows the SE. For example, in the original (judging by the GOUT and some scans I saw etc.) in the first shoot-out, when it cuts between the rebel soldiers and the stormtroopers, the shots of the stormtroopers are darker and more blue than those of the rebels (which I suppose is because of the smoke). Also the over-all colour of the walls should be less white-with-a-slight-cyan-tint and more white-with-a-slight-dark-blue-tint.
