This is what was in the source code, which seems to be exactly what you have.
Maybe it has something to do with the way POV-Ray does math through SDL vs
through compiled code (float vs double, etc)

#declare SRGB_Encode = function (C) {
 select (0.0031308-C, C*12.92, C*12.92, 1.055 * pow (C, 1/2.4) - 0.055)
}

#declare SRGB_Decode = function (C) {
 select (0.04045-C, C/12.92, 1.055 * pow ((C+0.055)/1.055, 2.4))
