Do zoom in to verify, though: you have a third grid in the mix (the display screen) which could also cause moiré to appear. If that’s the case, the visual moiré changes when you change the magnification.
The effect of the demosaicing method on the appearance is coupled to an overall “sharper” or “softer” look: if you diffuse the fine details a bit more, the “grid” becomes less well defined, so the moiré becomes less visible.
