That's such a load of BS Paul. I've seen and taken many high ISO shots that both have & haven't displayed vertical banding. Unlike regular noise, the banding pattern is, to me at any rate, highly undesirable & very difficult to counter in post processing.
And I didn't need to scrutinise it at the pixel level to see it. I guess there are none so blind as those who do not wish not to see.
