In the color calibration page, at the end, the "caveats" section says:
"Some cameras, most notably those from Olympus and Sony, have unexpected white balance coefficients that will always make the detected CCT invalid even for legitimate daylight scene illuminants. This error most likely comes from issues with the standard input matrix, which is taken from the Adobe DNG Converter.
It is possible to alleviate this issue, if you have a computer screen calibrated for a D65 illuminant, using the following process"
This is also true for at least some panasonic consumer cameras (gh1 and g7). Using your recommended method works perfectly, even with an uncalibrated monitor. The deviation is such that, even if the screens white is not true d65, it is so much closer to it than the default values. My g7 shows a strong yellow cast with the default camera reference setting in the white balance module. Overall colors are much better behaved with custom white balance in the white balance module (since you're feeding much saner values to the input color profile), and you can use the daylight setting in color calibration. You can then further calibrate your camera/lens setup with a color checker.
TLDR: perhaps you don't want to encourage users to use uncalibrated screens (which makes sense). However, even an uncalibrated monitor's "d65" is better than the coeffs of some cameras. Maybe include that in the doc with a warning that it is not the ideal workflow. An amateur may buy a color checker and calibrate his/her camera. An amateur may or may not be able to justify the cost of a screen calibration device (my camera/lens combo cost less than a screen calibrator). Pros should calibrate everything.
