I should have mentioned that I use PS 2015 and associated LR...I do wonder why you suggest a DNG profile as opposed to ProPhoto.The color temp of my LED lighting is quite close to 2800 K...otherwise, I understand.
After some putzing around...adjusting the WB in LR to "Auto">cover the whole image using an adjustment brush and add some red using that color box at the bottom.In PS>insert a color spot in an area that has about a 210 RGB>add a levels layer and adjust greens to about 185 and blues to 130>drop the intensity to taste. I would hesitate taking this to the bank though.
