Actually, at 100% veiw, I see pattern noise even without boost (no +/-
compensation on RAW converter). If you don't see the pattern noise (on the
smoky sky) at +1 your monitor is too dark, just try +2 you must be able to
see it.
I have not try to print it but it should be visible on the brighter area.

Hello CH,
Where do you see the problem in this image? I opened it in DPP and
don't see obvious pattern noise at +1 stop (but I'm looking at an old
macbook screen which is maybe too dark). Is the pattern visible when
printed?
All the best,
Iwert
