Kamvas 22 plus sRGB coverage

Hello friends,

I would like to ask about the sRGB gamut coverage the Kamvas 22 plus has.
When I calibrated mine I got a somewhat lower coverage than I expected at 93%.

I someone can help me with the calibration of the device I would be extremely happy since I am completely new to it.

Further question: Do I need a calibration device that supports quantum dot technology? As of now I am using the Spyder X pro with displaycal software(mode: Generic, correction: Auto(none)).
