Of course. I verified this before posting. Try the DPR samples like this one:

Or this one:

Another 20MP APS-C sensor:

Or even this one from a 1" sensor:

These might have some slight blocky posterization that's typical but not that grainy, almost maze-like structure.

I don't find those better though.  The blockiness in the sky in those is to me more of an issue than the "grain" you see in the new Quattro samples (especially in the second link), though I still hope it can be reduced  somewhat from raw.

I will say though it seems likely Nikon et. al have a more advanced JPG engine than Sigma has, probably carefully customized for the camera.  But I don't think the result is "awful".
