I see the dark reading does not need to be taken as often with the i1 Pro 2 & can read up to 1200 nits compared to the dark reading every 10 mins & only 300 nits for the i1 Pro 1. No self calibration feature either but they seem to measure the same with dark readings.
I currently just use my i1 Pro 1 to profile my i1 Display Pro so I dont think I will gain much of an advantage using an i1 Pro 2.
The requirement for dark reading is not a problem, since you will use the spectro to create a meter correction table, so you will use it for just 2-3 minutes max, after the initialization.
i1PRO1 is fine for about 3-4 minutes, while the timer can say 10 minutes, it will drift after that 3-4 minute period.
The peak output capability for 1200 nits of i1PRO2 or 5000 nits of i1PRO3, is a capability not required when you will use the meter to create meter correction table since always you will create the meter profile with about ~100 nits white pattern with HDR displays.
There a lot of info for X-Rite meters explained there
. (about how Built-in Wavelength Calibration Technology works etc.)
For example, X-Rite i1PRO1/i1Studio/ColorMunki Photo/Design just using the calibration plate (ceramic white tile) for just to take a dark reading (and can be OK for about 3-4 minutes after the dark reading, before starting to drift slightly). i1PRO2 is more stable over the time.
With X-Rite i1PRO1/i1Studio/ColorMunki Photo/Design, you can use a dark surface where the meter will contact to take the dark reading, for example when you will have mount the meter to a tripod, you can close the meter optics with a dark cloth, a CD case or your finger for example... while with i1PRO2 if you do the same, since it will require its own calibration plate with the serial matched ceramic tile to initialize.
