Agreed. But they show sharpness as 3 while viewing in camera itself. Is there any way to reduce that to zero?
For Raw, it does not matter what it says. Raw does not use or include any of the camera settings. Raw is Raw, meaning, it does not use any of the camera settings. (Raw mode of course does use exposure settings, and AF mode, and there are settings like Raw file compression, etc, but Raw file data does not use Sharpening or Vivid or Contrast, or whatever tonal options).
Raw data is different than RGB data, meaning, the camera cannot even show a histogram, and cannot show the preview image on the rear LCD. So, what Raw does is to also embed a Large JPG image in the Raw file. This JPG image does use the camera settings. We see that JPG data on the rear LCD and in the histogram. Camera settings do affect the JPG view, but not the Raw file.
But later, when you download the Raw file to the computer, there are no camera settings in the Raw file. The settings are in the Exif, but the settings are not applied to the raw file. We make adjustments to convert the Raw file with the new settings of our choice, after we can actually see it. This is one advantage of Raw.
Two exceptions:
Nikon Raw software does read the Exif and can apply most of those settings to the new RGB image it creates. Why we would want to do that is a mystery.
(when now we can actually see what it needs instead).
Adobe Raw software does (optionally) try to approximate camera White Balance, but only White Balance (the As Shot value). No other camera settings can apply to the raw file. The Raw software has its own Sharpness and other settings to be used, after you can actually see what it needs, and see what actually helps. The raw software has defaults always used (for Sharpness too), or you can modify defaults for individual images.
