Lightroom initially shows you the Nikon embedded jpg until it produces its own based on its translation of the RAW data. You have to use Nikon's software to get RAW files interpreted according to your exact camera settings. In addition to saturation, there are also contrast differences.
I, at times, for comparison purposes, just pop out the flat-rendered jpg. You have quite an artistic vision. I was just wondering how that manifested here. It's obvious that there's more violet than one would normally see.
