I believe that's how Spectraview II calibrates on all supported monitors.
"High bit depth internal Look Up Tables (LUTs)
Each LCD display monitor supported by SpectraViewII features three internal 14, 12 or 10 bit LUTs (depending on model). These tables allow very precise adjustments to be made to the display's Tone Response Curve without reducing the number of displayable colors.
Fully automated calibration
By making adjustments directly in the display hardware, optimal settings are configured without any user interaction. SpectraViewII communicates with the display monitors using Display Data Channel - Command Interface (DDC/CI) which is a two-way communications link between the video graphics adapter and display monitor using the normal video signal cable. No extra cables are necessary.
Monitor Profiling
After calibration, the display is automatically profiled and highly accurate ICC/ColorSync color profiles are generated and automatically registered with the Color Management System. These profiles use the Bradford Chromaticity Adaptation matrix."
My EA2444 UHD monitor is a fully automatic calibration.
