Except in the most exceptional circumstances, I nearly always err on the side of not blowing out the highlights. Of course, I shoot bracketed exposures quite often, so that increases the dynamic range of my D850 by quite a bit.I was thinking "tripod" when I said iso 100, but I certainly understand why you didn't have one in this case. Nevertheless, I see no noise in your posted image. A busy scene helps .
My suggestion still holds. I still think blown highlights is a much more serious problem than noise in shadow areas, but that's just my approach.
The point is that by increasing your exposure by +0.6 EV, you are very unlikely to have lost your highlights because the Histogram in the camera is referring only to a hidden camera-processed JPG which is contained inside the NEF.
The Nikon Histogram does not give accurate information about the RAW file itself.
You can test this in RawDigger.
I find that increasing exposure (so that I have more data in the shadows) to work with while processing improves my results considerably.
I am familiar with the mathematics and I understand it. I have had a copy of RawDigger since April, 2006, and I have examined many of my photos using it. The argument is convincing until you find an image that has less than 5% overexposed highlights but those highlights are in important places that you want to preserve. I see no way of being sure that they are preserved except either (1) taking the picture, bringing the raw file into RawDigger and examining it, or (2) underexposing slightly when I take the picture. Since option (1) is impractical 95% of the time, I choose to use (2).This youtube movie explains the science behind RawDigger:
It does start with a mathematical explanation but if you want to skip that (although the info is important!), just go to the 2 minute marker on the video.
There is a fully-featured 30-day free trial download on the RawDigger web site.
I suggest that you download it and examine some of your own RAWs because you may be fairly horrified by what RawDigger reveals!
This video is another very good explanation of the difference between exposing for a RAW as opposed to a JPG.
