No they don't
The DP2m is perfectly usable, if we like it, in landscape, objects, texture. But even in landscape, there is numerous photos over the web who show the flaw. The red channel is out, by a large margin. Skin tones contain red and this is were we can evaluate a sensor "equilibrium".
The DP2m have issues with reds. Of course when you know PP, all is fixable. The brown gradations are more than off. Just see the SIGMA flickr and you will understand what I mean.
In the link above, I do not really care about the picture but what is said above ^^ 5100 USD ?? Hooo Blimey
I judge a camera on the delta between what I see, the reality (and I have very good eyes, especially in colours), and what the camera see. The delta between the reality and the DP2m reality is... well... huge. This is not the case with the DP3m.
When I made the article on Lula about the DP3m, the very same pal rapidly attacked me on one of his article. Roughly he said I'm a poor amateur who said BS and that the colour delta between DP2m and DP3m was just in my head. Well... he was very wrong and many posts over DPreview proved that I was right. There is certainly a difference between bloggers and photographers.
Same goes with Leica. The delta between M9 CCD and M240 CMOS is huge. Leica lost his soul over this. Many seen it, many seen it but was too fan boyz to say it and so on...
I love SIGMA but I continue to think that the SD15, Dp2s, DP1s, DP2x, DP1x sensor was better in colour than the new foveon chip period. Resolution and acutance lured and dazzled the new comers in foveon side, that's all.
The DP3m is the most accurate, colour wise, (with the SD1 coupled with some lenses) of all the new foveon generation.
When you work with cameras and many brands, you see it asap.
