I'm wondering if you could do a second render that removes the green/yellow cast. In another thread we were talking about how it's likely a side effect of a color space conversion from DCI-P3 without white point adjustment. I've made a 3D LUT that gave me pretty dang good results on the BvS trailer, could send you that to see if it gives good results.

Here's the LUT: https://mega.nz/#!byBj2YBA!ZawROR_rbKu98...bsulCYLP4Q

You can apply it via AVISynth with the Cube() plugin or via any other software, not sure what you use.

I find this movie to be incredibly good looking without the green/yellow tint.

I think the coolest thing would be to see regrade from KK650

I think this LUT is probably better than what KK650 has done because it's not a guesstimate, but rather created by using a set of color conversion operations in Photoshop to reverse the (assumed) source of the problem, so it should - assuming the theory is correct - be 100% accurate. Doing it by hand creates a lot of variables - gamma, the color space you're doing it in, etc. Did a few tests earlier with the screenshots posted in this thread and I was personally pretty happy with the result. But of course I won't argue with taste.

Could you show couple screenshots?

Sorry, I'm pretty lazy.

Here's the ones I did with the trailer at least:

But you can just take the 3D LUT and apply it to screenshots in Photoshop or some other tool.

Looks and sounds fantastic!

To do list: per #52 remove the green/yellow cast and per #60 add some grain on IMAX frames.

I haven't seen it in motion yet, but it seems that you went the hybrid route, overlaying the Blu-ray on the IMAX sequences, but you have not added grain on the IMAX sequences to match the Blu-ray, or so it seems when looking at this example, 'cause the middle slice is grainy whereas top and bottom are smooth:
