DNG vs CR2 Display

Hopefully someone can explain what is going on here. I noticed while working on other images that DNGs in Capture One 6 Pro have very strange color and exposure, so I took a test shot to compare how Capture One processes an identical image; one CR2 and one DNG.

I have a CR2 image, and a DNG copy of that same image (created with Lightroom 4). The CR2 image appears in Capture One as I would expect, but DNG files are darker and have stronger contrast. See the example below; CR2 on the right, DNG on the left, with no edits to either, nor changes to the default ICC profiles (5D Mark II and DNG, respectively). The histograms are completely different.

Can anyone explain what I'm seeing, and hopefully enlighten me to a solution? This DNG is supposed to be compatible with Camera Raw 5.4 and later.

Here is another example. This one is a CR2 on the left, and a DNG converted from the CR2 by Capture One:

I'm experiencing the same problem. My CR2 files (from a 5D Mark II) looks fine in Capture One, but when the same files are converted to DNG by Lightroom 3 or Adobe DNG Converter the colors become permanently messed up. It cannot be fixed by changing the white balance or the base characteristics settings. I tried switching the base characteristics from "DNG File-Neutral" back to Canon EOS-5D MkII-Generic and the colors got even worse (sort of florescent/solarized). Very frustrating!

Native RAW = Apples
Converted DNG = Oranges

We have built Capture One to support many Canon RAW files and have built calibrations to specifically render the Canon RAW files to their fullest potential. We have also built an Adobe DNG profile to do the same. The problem is that you are comparing the two... as we have not built a Canon 5D Mark II DNG profile, we treat the two files as separate entities (as once a CR2 is converted to DNG the information is now of a different value) and thus the information available is rendered differently.
Think of a DNG like a JPEG. Every camera (Canon, Nikon, Sony, Panasonic, iPhone) will shoot a JPEG and yet all of those JPEG files will look different. Same type of file but different ways of interpreting the data. The same holds true for a DNG, same type of file but rendered differently... add that to the fact that you are comparing two separate file types and the differences are multiplied.
