First, a Saturation sweep will not really show the impact of Drift Compensation, as there are not enough patches used.
To see the result of Drift Compensation you need to perform a large initial profile (with Drift active).
Make two LUTs from that profile - one with, and one without Drift enabled.
Use each LUT in-turn, and re-profile with a large patch set.
Then look at the dE value for each verification - all the dE values for every patch.
With Drift active you will see an improvement in the total dE.
But, for a quicker test to see if the display has drift just measure the same patch colour over an extended period of time and compare each reading.
You can do this with 'Measure and Log' mode, as this will record each reading in a CSV sheet.
(You can use the slider's 'Jump' function to change the patch in between each reading to prevent burn-in, etc., and use filtering on the CSV sheet to remove the readings for colours you are not interested in.)
And for Dark Patch measurement, within LS you can select 'Average Low Light Measurement' so 'slow' dark patch readings.
But, it is the CR-100 that actually set the time for reading any patch in Closed Loop mode (and DIP Mode!).
When the probe is satisfied it has a stable reading it tells LS to move on to the next patch.
You can control how quickly/slowly the probe integrates its reading using the values on the 'Options' page.
Info on the different probe settings can be seen on this page, and how the settings change the read times at different patch luma values.
All 'Average Low Light Measurement' does is force the probe to read the same patch a number of times to 'check' the dark readings...
Hope that helps.
