Klaus, thanks for interesting info, didn't know that colorimeters comes with custom tuning for particular displays.

Lprof provide data using it, but it's only luminosity but color temperature always still the same. And I'm not sure if it could be trusted. Can you please tell more about ways of measuring ambient lighting using camera? If there is article about this, URL would be very appreciated.
