Hi Mike,
I've just read this thread and I think I might have an answer of sorts to your problem, although you may have already followed this procedure. The NECs are excellent displays IMO, but there are some settings you have to take care of before you do you first calibration with Spectraview(or any software). It's been a long time since I've had to do all of this with a new NEC, although I have three of them currently. You will find all of this info in the NEC manual as well as the Spectraview Guide. Since I have neither here at the moment, as I'm in the process of moving, I cannot readily recall the exact settings to take care of, but you will find the procedure in the manuals as mentioned. The idea here is to make sure all of the user available display settings should be set to neutral before calibrating. Then you lock out the possibility of anyone changing any of those settings, including yourself of course. It may be tempting, under certain circumstances, to tinker with the display settings to lighten, change contrast etc., but of course that would negate the calibration settings. Please take a very careful look at the manual and guide Mike, since your numbers seem to be in the range of a good calibration, although your prints would seem to indicate otherwise. And as Wayne mentioned, make sure you have at least the minimum illumination for your prints. I've learned in this thread that there are apparently 5000K LEDs with a CRI perhaps as high as 95. I'll be setting up a new viewing station at home, so I'll certainly be looking into the possibility of the LEDs instead of fluorescent, since the new energy efficient 5000K bulbs cannot get any higher than CRI 80.
I hope this helps in some way Mike.
