Very interesting, and a case for using RG1G2B or RGBW sensors in cases where this can be a problem, I guess?

I wonder if it isn't possible to program RAW software to simply ignore one green sensel per RGGB quadrant and amplify accordingly? It might produce other problems but you could use it on the trouble spots.

I think you misunderstood me Macx. The color-channel imbalance problem is not that there are two green pixels for every red and blue one. The problem is that each green pixel is about twice as strong as each blue or red one. See my exchange with Cani here (including the text quoted from prior posts) for further explanation:
