Can I reproduce a Nikon Z6 JPEG’s in-camera processing from the RAW file?

I’m trying to match the look of a Nikon Z6 JPEG from the corresponding RAW file, including the camera’s in-camera processing such as white balance, contrast, saturation, sharpness, and noise reduction. EXIF only shows broad labels like “Normal,” but not the exact settings or algorithms used.
In one case, the camera JPEG looks much better than my default RAW conversion for a high-ISO night-sky image, and I’d like to recreate that same processing at full resolution from the RAW. Is there any way to determine the exact in-camera processing Nikon applied, or to reproduce the embedded JPEG look from the RAW?

The only app that can correctly recreate the algorithms used for the embedded jpg in a RAW image is Nikon's own. Everyone else must attempt to reverse-engineer, with varying degrees of success. The algorithms are proprietary & not published.
It's only available for Win & Mac & has recently been split out to a new app [which I wasn't a fan of & now won't run on my old Mac so I can't test newer versions.]
NX Studio is the new version, ViewNX-i the old, depending on the age of your system.
This by default will reproduce exactly the processing applied to the embedded jpg, but of course at higher resolution. You can then export as tiff or jpg for further editing.

Not from EXIF alone. Tags like “Normal” don’t reveal Nikon’s exact processing values or algorithms, and those in-camera JPEG recipes are proprietary.
In practice, the most reliable way to match the Nikon Z6’s JPEG look from a RAW is to use Nikon’s own software. Community answers indicate that Nikon NX Studio (and older ViewNX-i on older systems) can reproduce the camera’s embedded JPEG rendering from the RAW, typically at full RAW resolution, because it understands Nikon’s private settings better than third-party converters.
Other RAW apps have to reverse-engineer Nikon’s processing, so results may differ—sometimes a lot, especially for things like high-ISO noise reduction, sharpening, tone, and color.
So:
- You generally cannot determine the exact in-camera processing from metadata alone.
- You usually cannot exactly recreate it in non-Nikon software.
- For the closest or exact match, use Nikon NX Studio to open the NEF and export a full-size JPEG or TIFF.
