While I'm at it, that document contains a very questionable statement about the "black point" of sRGB, suggesting that the "black point" has a "veiling glare luminance" of 0.2 cd/m^2 (and indeed that suggestion appears further in some of the formulas in that document). Is it true that the "sRGB black point" (what sRGB defines as black) has a luminance of 0.2 cd/m^2 (absolute Y = 0.2) rather than 0 cd/m^2 (absolute Y = 0, the start of the absolute XYZ scale)?
