It's easy enough to check. In windows go to the control panel and click colour management. In the window should be your ICC profile generated by the xrite software.
In Photoshop click edit -> colour settings. Next to the text that says "RGB" click the dropdown box and look (BUT DON'T SELECT) at the profile called "Monitor RGB" If Photoshop has loaded the colour profile correctly then you should see it listed next to Monitor RGB.
What settings have you set in the software for calibrating? It would be strange for the black point to be off so far on a monitor profile. It is supposed to rarely change even on quite dramatically different screens.
Also your Dell monitor has a 82% gamut coverage for AdobeRGB. This means it can display more colours than a normal screen. It also means that any program that doesn't read your colour profile will display colours wrong. Welcome to colour management hell.
By the way if you ever want to see the internet correctly I suggest you right click on your Google Chrome icon in your task bar, then right click on the popup "Google Chrome" and click properties, then append " --enable-monitor-profile" to the application executable.
