The ISO 100 shot seems to have grainier noise than the ISO 6400 shot. I see this when looking at the full-size (100%) widget view in a number of areas, such as the windows and bricks at the building corner, as well as the area above the black car at left.
Is this related to the ISO invariance, or to some other factor such as the RAW processing software used or shot-to-shot variations?
Based on what DPReview presented here, it would seem that push processing on the A7Rii does have a penalty in increased or grainier noise. So this, plus the RAW conversion artifacts, IMHO would be a reason to normally photograph at the camera's indicated exposure, or perhaps just one or two stops darker if you're trying to preserve some important highlights. Am I missing something?
