Maybe, maybe not. I think as Jonas points out, some people are more sensitive to it then others. There may in fact be some sample cameras that do produce more VPN than others.
I do agree that the issue is WAY over blown.

See, you have just verfied my point. The VPN is so slight, you really have to look for it. I will take a look at your NN technique though. I have not attempted to isolate noise by color channel.
Thanks

This is about as bad as I've experienced VPN. In the shadows , upper left. Given the conditions, I think it is not bad at all. There is a bit of random noise in the tires, but I only see it at 100% crop.
