Chris, I cannot replicate your issue....
First try setting your monitor profile to sRGB as a test... if that gives a clean result your monitor profile is either corrupt or the wrong variety... (I'm not sure how you tell but there are different profile versionings)
I sent a DNG to Black and White in Lightroom and opened it in PSCC2014... The resulting DNG file in PS is prophotoRGB and 16bit. Using the Info eyedropper it is neutral all over as expected and is visually the same as in Lightroom. I'm testing this on a MBP 15" with 10.10.2 and Lr5.7.1 with PSCC2014.
Here is a screen shot with Lr and PS overlaid:
