Chris, he is asking spectral power distribution (energy per wavelength). Colorimeters need to know this to auto correct themselves: where they are sligthly different from standard observer, calibration app uses supposed/sample spectral power distrubution to know if it was over measuring or under measuring because colorimeter reports its spectral sensivities (its "raw non standard observer"). It does not work exactly as this, it accumulates all correction per wavelength in a 3x3 matrix, but i find the above explanation easier to understand for general public.
Usually and without further knowledge of an specific display: -sRGB only displays: White LED (WLEDFamily_07Feb11) or WLED PFS phosphor "crippled to sRGB" (PFS_Phosphor_Family_31Jan17) -P3 multiedia displays: WLED PFS phosphor ("cheap", Panasonic VVX17P051J00) -Exactly P3 displays (Apple): bundled in DisplayCAL, WLED PFS phosphor for mac. -AdobeRGB green and P3 red: WLED PFS phosphor ("premium" HP_DreamColor_Z24x_NewPanel) or QLED (not bundled, but there are samples in DisplayCAL database in some Asus PG models)
It's a multimedia P3, you can use on of the user provided 3nm CCSS in the link above (do not use sRGB simulation) or the provided 1nm correction by Xrite WLED PFS phosphor ("cheap", Panasonic VVX17P051J00). This 2nd one is labeled "PFS phosphor" on CCprofiler/i1Profiler. I'll choose the one by Xrite unless you find calibrated whitepoint to be off.

The online U2723QE User's Guide states = LED backlight
Dell does know what LED options you see in DisplayCAL.
