I wouldn't exactly agree.
It is true that sensors will have their lowest noise floor when cool. So non-contact modes are usually preferable.
But many sensors also now have thermal compensation to keep the readings inline as they do change temperature, and the new i1 Pro 2 with it's aluminum chassis does a great job of thermally isolating the sensors. Lastly sensors that aren't compensated and will fluctuate with temperature like an i1 D2, warming up the the sensor is about the only way you'll be able to get repeatable results.
So meters work best cold.
Good meters aren't that sensitive to temperature.
Meters that are sensitive to temperature need to be held stable.
