The 3D grade looked too yellow, while yours look too blue to me. On a sunny day, a sky does not cast such blue shades. You should also check the white balance. It should be slightly warm. Just a suggestion from a student of cinematography.
Have you actually downloaded and seen the Titanic IMAX release in motion? Screencaps can be misleading and look colder and more contrasty when viewed in a size smaller than their original size on a monitor, you get a better idea of their actual saturation and contrast when viewing them at full size and even better when viewing the film in motion.
I can see that the blanket yellow tint on the Titanic 3D blu-ray has been fully removed and the colours are balanced beneath that blanket tint. What I mean by the colours being balanced is that there isn’t a blanket tint on the regrade. If I go any further and remove more yellow, then I would start adding a blanket blue tint.
I have had one or two releases where the release felt cold after removing all the blanket yellow tint, even though the colours were balanced, so I had to create another release where I added back part of the blanket yellow tint to counter that feeling. This was especially the case with the Magnificent Seven (2016) regrade I did, I had to create two releases and the warmer one was my prefered one but there were quite a few people that prefered the more balanced colder release as well, they said that to their eyes it had more ‘pop’. I personally don’t feel that is the case here with this Titanic IMAX regrade when watching it in motion.
If you get the chance, check out this release on Myspleen, its currently freeleech there so it won’t affect your ratio, seeing it in motion may change your mind.
