The first color corrected screencap with the flames really looks bad - too much contrast, burnt out, oversaturated.
The second (Marty's close-up) is just too bright. On that particular frame it's not really a problem, but applying that to the whole film... it would probably be wrong. Brightening up too much is a common problem in home-made remasterings.
Honestly, I don't see the problem with the DCP's colors. I'm not saying I couldn't imagine even hotter colors for the movie, but they look good and consistent.
