FYI.. FINALLY got a response from Xrite:
We've done some additional research into this matter, and it would appear that you are possibly experiencing an issue with Mac/Dell differences in how the display information is being delivered.
Here's a comment we've received from Dell.
We are well aware of this issue. It is a required feature for monitor EDID to specify support of both RGB and YPbPr. This is especially true in HDMI where it can be connected to DVD players/game consoles etc. But the Mac OS somehow default to YPbPr color space when it read the monitor EDID. In general YPbPr is for movie and not text, therefore there is a lot more color/sharpness enhancement(like a TV). When viewing text in such mode, the text will have some degree of overshoot/shadow and color might be over-saturate.
The only way on monitor side to overcome this is to remove the YPbPr support in monitor EDID. This is not feasible at least in HDMI. We may do so in DP but may cause other problem with professional graphic designers. So having the patch to “overwrite” the EDID is the way around it for now. Apple as you see is aware of this, whether they want to “help” the industry and do the right thing, we are not sure.
So, to make a long story short, this seems to be something that both Dell and Apple are aware of, but there's no resolution currently for this situation.
