I'm going to post this here for anyone to know and to save them from the miserable task that is calibrating your display for the Xbox One. I've tested my monitor thoroughly with both my laptop and my Xbox One, both connected with HDMI. My monitor supports both limited RGB and full RGB.
Here is what I found:
The dashboard can be unreliable as a source to calibrate your display. In limited RGB (Color space: TV, monitor set to limited) it still outputs Blacker than black levels and Whiter than white levels. In Full RGB it doesn't expand it correctly. It still outputs in limited and everything below 16 and above 235 is clipped.
Internet Explorer is even weirder. It always outputs Full RGB with the Xbox one set to limited and clips in the same way the dashboard does in Full RGB. The only way to get correct colors in IE is to set your Xbox One to limited (Color Space TV) and your display to Full (black level High or Normal). When your Xbox One is set to Full RGB it will always clip black levels and white levels. This is where much of the confusion comes from on several forums. Many people use IE to calibrate the display with test images.
With IE showing the correct colors, the Xbox One still has a rather low gamma curve. It is unable to output black level 1. This isn't related to my display as my laptop is perfectly capable of showing black level 1 unless I lower my gamma to something near 2.4-2.6.
When set to Full RGB, the Xbox One clips the first 3-4 black levels and the last 3 black levels in games. This means it has a range of 4-251 instead of 0-255. This in combination with the already low gamma curve crushes blacks considerably. In limited RGB, only the first and the last black level (1 and 234) are cut off due to the low gamma setting. This is still considerably better than Full RGB and I think most developers will calibrate their games to limited anyway.
You can test the above in-game with in-game calibrations. For instance, in Destiny, the lowest brightness (Brightness setting 1) the background is still somewhat gray against the dialogue that shows the setting. In Full RGB it's all black. Judging on it's brightness, that gray background is either 3 or 4 so it should be shown even with the low gamma curve of the One.
My laptop shows zero difference on both Full and Limited RGB when testing black levels (with the monitor set correctly for the range), even when adjusting the gamma to ridiculous levels. While the Xbox One is considerably darker in Full RGB. Conclusion is that the Xbox One has a better picture quality in limited. So unless you game on a monitor that doesn't allow you to change your black level to limited RGB, use limited. Full should only be used when gaming on a monitor that doesn't have such a setting.
I don't know exactly why the Xbox One outputs Full RGB incorrectly, but I think it has something to do with some sort of scaler that is placed on top of the games to handle non-native resolution, and rescaling the game when in snap mode or returning to the home screen. This scaling process is probably unable to output in Full RGB correctly. So even when set to Full RGB, the game does not output Full RGB natively. This is pure speculation though.
