Sigma's best vs. their best . . .

I saw the article about the Sony A7r III sample photos in the image comparison here on DPreview, and I decided to take a look. I changed the A7r II sample to SD Quattro H S-Hi version, and I switched the Sony A7r III image to the Pixel-Sift version. I think the following samples I captured from my reviewing of the Sigma image vs Sony, Nikon, and Canon images are at least a little revealing. What I'd really like to know is whether the processing was done properly on that raw image from the Sigma camera. If someone can make a significant improvement, I'd like to see it.

Go ahead and look for yourself:

To me there are advantages of the SD Quattro H (primarily the lower price, but also the lack of color moiré). It does seem that the ultimate image resolution comes from the Sony in pixel-shift mode though, which is what I would expect, because it almost simulates a 42 MP Sigma SD Quattro F, which is a camera that does not exist. Maybe this will motivate Sigma to make that 50 MP SD Quattro F that I have theorized though. I think that would be wonderful.
