Quite interesting link. However unless we're looking into completely different pictures, I can see lots of examples that show nice and sharp black-to-white transitions and really, really bad rendering of colour edges with lots of ugly interpolation artefacts. That red speedometer needle is the best example imho - tack sharp black numbers and ragged red needle. As I can't see similar issues with Sigma's pictures, I'd say this link illustrates my point perfectly.

We are not looking at different things. I seem to be looking at what we can see, you seem to not be doing that.
We see much more detail all over, and yes, we see some colour artifacts from a bad RAW converter. We were not discussing the colour, though, we were discussing the extra "detail", which is very apparent (it is in luminance, not in colour space... both get extracted from the RAW data in different ways).
