The i1D3 seems to drift in temperature of about 400K in a duration of 30min when on a warm screen (CCFL or plasma) despite it being internally compensated.
I have asked this in the past, whether I should wait till the i1D3 warms up on screen and only then calibrate or the meter should be at room temp' and calibrate from a tripod.
ConnecTEDDD answered that the noise floor of the i1D3 sensor raises with temp, and it should be always at room temp to be accurate especially on hot displays like plasma.

To mend this while still using contact calibration,
I use "interactive display adjustment" to adjust the white point to 6500K with the meter at room temp' and 10cm away from the screen.
Then I cancel the current calibration because there is no option to set the white point without continuing to calibration,
and start a new one with the meter on screen but with both black and white drift compensation.
This gives me nice and even temp' across the greyscale thanks to argyllCMS's drift compensation.
I want to make sure everybody is aware of this.
