Hi Tom,

I think you meant ISO 125-200, as the exif data shows.

This is consistent with what I find: the texture appears in jpg Large fine at about ISO200, builds up to 800, and at 1600 disappears in favour of a different, more "conventional" type of noise. It's as if a different processing algorithm kicked in between 800 and 1600 ISO (I haven't gone into more detail to see the exact ISO at which the change occurs). See my post 8 days ago above.

What I have also found is that using EXR HR mode attenuates (without completely eliminating) the canvas texture effect.
