I've got to correct myself. The cover and the calibration strip have
almost the same distance from the sensor. The strip is just a thin
sheet of paper or plastic that is placed between the screen and the
cover.

How about the following calibration scheme?

- Switch on the lamp and let the warmup period pass by.

- Place the sensor in the middle of the white strip

- Do the white calibration.

- Move down the sensor until the results become much darker plus some
  additional steps.

- Switch off the lamp for a short moment, and meanwhile do the black
  calibration.
