Probably doesn't matter, as long as you're consistent. Either always cold, or always after a specific amount of warmup.
My protocol: TrainerRoad ramp test every 4 to 6 weeks, do my standard BC 20 minute warmup, calibrate the Kickr then do the test. I don't calibrate outside of that.
Having measured with PM pedals, crank + Kickr at the same time over several workouts, the Kickr reads about 10% higher (so easier on you) for the first 20 to 30 mins of a workout. The pedals and crank were consistent throughout, 30 to 40 mins in they all line up.
I always use the Kickr for power indoors, as a result of my testing I used to bump my workouts up 10% for the first half, but eventually forgot about it and just rode them as is. I train at 7am straight out of bed so easing into Vo2 max ain't a bad thing really.
