On this image it looks like it is a small problem.

Definitely, but it does show the importance of exposure. Foveon sensors aren't as inherently noisy as X-Trans but SIGMA's chroma NR is lacking by comparison. So we have to have half a mind on exposing for the sensor, not just the scene i.e. intelligent ETTR.

Or just accept colour blotching
