Hello, i wonder if the Display calibration is stored inside the UEFI and can be accessed to improve the display quality.
The device is a Intel Core M tablet with a Samsung 1080p display, bios can be found here: http://www23.zippyshare.com/v/AptZQQne/file.html

Edit:
Maybe in one of the VBT modules?

VBT HASWELL BIOS_DATA_BLOCK Intel(R) HSW Mobile/Desktop PCI Accelerated SVGA BIOS Build Number: 1038 PC 14.34 02/17/2015
VBT HASWELL BIOS_DATA_BLOCK Intel(R) HSW Mobile/Desktop PCI Accelerated SVGA BIOS Build Number: 1215 PC 14.34 12/13/2012

Edit2:
Found more information about vbios: [Guide] Transfer of specific Intel VBIOS settings by using Intels BMP tool

Well, i found a solution. It is possible to activate edid chromacity control via Intels BMP tool.
With adjusted and reprogrammed edid values it then works like a calibration.
