Un-sure what to say. I did notice something when I first had the D810 which I hadn't realised previously with the D750. In picture control the camera adds sharpening, contrast etc... so I have set my camera up to neutral and zeroed everything, my thinking you are doubling up on processing.?? I can add my own changes in LR.
For the BT photo on twig this was my settings in LR, there was some sun on the BT back . The settings below are typical for my bird photography, although Clarity is a little high on this occasion.

I have only listed the relevant sections as typing one handed.
Maybe worth comparing to the above to see how you get on.? Some of the experienced members from the bird section who are now banned, give the above starting points for me and I have stuck with it in general. I can't be bothered to go into PS and do selective stuff.
Hope the above helps.
