For my fellow Nikon D810 shooters who recently updated their Lightroom and/or Camera Raw apps, you may be noticing that your images appear a bit flat upon import. That is because Lightroom 6.1 and Camera Raw 9.1 ignore the Adobe Standard Color Profile from Nikon D810 raw images. Instead, they default to the next available profile in the Camera Profile pop-up menu which is Camera Flat, so your images display with unexpected color.
Good news though ... below is the workaround until it's fixed. I just did this on my Mac, and after restarting LR, all is well. In addition, when I import new images into my LR library, they default to the Adobe Standard Color Profile. Nice.
