Applying Lightroom Presets with While Balance Settings
If you include White Balance settings in a preset applied to a Raw file, and apply that preset to a JPEG file, Lightroom tries to apply the equivalent white balance adjustment (but using the JPEG scale). Therefore, the White Balance adjustment on a JPEG (using a preset based on a raw file) is necessarily an approximation. We try to do the closest job we can, but results will vary somewhat on a case by case basis.
