Ethan, Roger, Warning: I am closely involved with PatchTool development ;-) Yes, PatchTool can open the dxmf file. It can also extract the data from the profile, if present and if the tag is recognized of course (!), with the aptly named "Extract Data from Profile" tool (this tool also works in demo mode without purchasing BTW). PatchTool will also show you the wpt tag. However, this is non-normalized emission data. In other words, the WhitePoint is not normalized to Y=100 and the display WhitePoint will likely not match a standard Illuminant. When you open the cxf file, PatchTool will ask you to select an Illuminant, because it expects a reference Illuminant, which is always required for reflectance measurement. If your display is nearly spot-on a standard Illuminant (i.e. D50, D65), this selection makes sense. In most cases it does not. You can however export the display cxf XYZ data from PatchTool in a text file and process it yourself. This is similar to RAW display data files generated by PatchTool, which are also generated for external processing by the user (which are also warned it should not be opened in PatchTool). Note 1: When a display measurement is made with PatchTool Display-Reader AND you measure your Display WhitePoint, the program can provide both a RAW data file AND a processed data file. The RAW file is for those who want absolute measurements, and is equivalent to the data found in a display profile; it cannot be opened in PatchTool, as mentioned previously. The processed file takes the RAW measurements and converts them (Rel-Col) between the measured display White-Point (which is whatever CCT) and a standard Illuminant. Because this processed data is converted to a standard Illuminant, it makes sense to open it in PatchTool (or any other program which expects reflectance data).

From: Roger Breton
I have not had much luck finding the measured display colorimetry using i1Profiler?
The software allow creating wonderful monitor profiles but the data seems nowhere to be found.
I have hunted all the directories I could think of to no avail.
The data seems to be incorporated into the resulting monitor profile but I would not know how to extract it.
You can extract the data from an i1Profiler monitor profile by starting i1Profiler and dropping an existing i1P display profile onto the measurement box. The "Save" button allows you to save the data out. Unfortunately the only supported format is dmxf. I see that PatchTool says it can read dmxf data.
The colorimetry used is the mysterious "XRitePrismDefault." What that is, I have no idea. Neither does Google for that matter.
