So, I have an i1 pro and i1 display pro.
I profiled the colorimeter using my spectrophotometer aiming the same point on a warmed up white led tv.
Then made some readings throughout grayscale.
Results from profiled display pro:
the readings were stable throughout grayscale
1st run of i1 pro:
2nd run of i1 pro (a reinitialization was performed betweend runs)
notice: the readings were unstable on the low end
As shown both meters give similar readings at higher luminance levels (30% and higher). i1 pro gives repeatable readings with luminance level over 15%.
BUT, it starts varying much from the display pro somewhere around 30% level.
The question is which meter too trust in that case and why?
I know that many pro - calibrators are using i1 pro + k-10, do the readings with profiled k-10 vary that much too on the grayscale low end?
