The 5th Element remastered with an Atmos track is a Sony Mastered in 4K movie, if your bd player and everything in between is xvcolor compatible you might want to try to watch it in that mode to make the most of the wider gamut. You have to select a user mode on the projector, and select the xvcolor colour profile. All the other settings will be locked. Give that a try. The source and the projector should be set to YCB, not RGB. When playing the movie, you should see xvcolor in the info screen when pressing INFO on the remote.
If you have a Darbee or a Radiance in the video chain, don't bother as they can't pass through xvcolor.
If that's not better, then make sure you're not in that mode (select standard color profile) and your calibrated color temp.
There is no reason for this title to look cartoonish if the settings are correct, although when I played it I didn't play it in Min4K/xvcolor mode, I'll give this a try.
