The image has no embedded profile, so it takes on your default workspace. Try assigning various standard workspaces, see if that affects the black separation. Start in Photoshop, assign ProPhoto, save it out and load into Lightroom, should look identical. As far as color tint, you may get better results creating a LUT based profile instead of matrix. I can see very slight tint in a few of mine, it may be that as good as this display is for the money it isn't in the same league as the more expensive NEC, etc.
Also the neutral performance is affected by the accuracy of the measuring device and number of patches in the target. Make sure your room is dim, hopefully the puck seals well against the screen but better to calibrate/profile in lower light. I'm assuming you're using the advanced mode in Palette Master Element, and that you've upgraded to the latest version. I use absolute black point, have had some problems in the past using relative.
