No. Lightroom 4.4.1 is the last and did not contain support for the D810. You can upgrade to version 5.6 (paid) or you can download the free Adobe DNG Converter and convert your D810 NEF to DNG where they can be read in older versions of Lightroom.
Thank You, after spending so much for the D810 maybe a few extra dollars for LR 5 is money well spent.
Probably a good idea... The tools get better each version!
