Using the original Little CMS software produces a Rec. In all profiles the media white point is D50, which has the XYZ tristimulus values (0.9642, 1, 0.82491).
The modification was made to make sure the sum of the tristimulus values of the colorants yields exactly the tristimulus values of the media white point. The ICC V4 profiles were created using a slightly modified version of Little CMS. The profile DCID65.icc, for example, is for images that have been displayed on a projector balanced to D65. I know there are some misunderstandings lurking and I want to make this perfectly clear. The chromaticity coordinates are x = 0.314 and y = 0.351. DCI This is the original white point for the digital cinema reference projector. D60 This white point has a correlated color temperature of 6000K.
D65 This is the white point used by the video color spaces Rec. The three profiles assume the display/projector is balanced to one of the following white points, respectively. The provided DCI profiles are supposed to be used with RGB images created and viewed on a display or on a digital projector that has the aforementioned gamut and transfer function. The same document specifies the transfer function to be a power function with an exponent of 2.6. Before standardization by SMPTE the specification was established by the Digital Cinema Initiatives (DCI). For historic reasons this color space is called P3. The document SMPTE RP 431-2:2011 D-Cinema Quality - Reference Projector and Environment defines the minimum gamut for a Reference Projector. That's the reason I named the profile Rec2020-Rec1886.icc. The introduction states that if it is shown that an alternative electro-optical transfer function (EOTF) will provide significant benefits without also imposing significant disadvantages, then this Recommendation should be extended to enable use with an improved EOTF. 2020 assumes that the encoding function of image sources is adjusted so that the final picture has the desired look, as viewed on a reference monitor having the reference decoding function of Recommendation ITU-R BT.1886. The normative reference is ITU-R BT.2020: Parameter values for ultra-high definition television systems for production and international programme exchange. Exactly this is assumed in the provided profile: a display that has the color primaries specified in ITU Rec. 1886 says that the reference EOTF for displays used in HDTV production and programme interchange should be a power function with an exponent ("gamma") of 2.4. That didn't happen, however, until the following recommendation was released: ITU-R BT.1886: Reference electro-optical transfer function for flat panel displays used in HDTV studio production. A common misconception is that the same standard defines the transfer curve of the display.
The normative reference is ITU-R BT.709: Parameter values for the HDTV standards for production and international programme exchange. I provide three different profiles for the digital cinema P3 color space with white points of D65, D60, and DCI. The XYZ encoding for digital cinema allows a variable white point. The white point of the colorspaces defined in Rec. The figures show the color spaces in the CIE xy and in the CIE 1976 UCS diagram, respectively. Three color spaces are commonly used in video and motion-picture productions: ITU Rec. If you view the images in a color-managed application, it can recreate the original image even if your desktop monitor is not adjusted to the same color space as the reference display. You can use the profiles to tag RGB images that have been created and viewed on a reference display or on a digital projector. When the same image data is sent to two well-calibrated displays, the images will match.

Professional displays can be adjusted to meet calibration targets within small tolerances. People rely on the calibration of a display or of a projector.
