# Corsair Xeneon Edge Color Calibration Script
# Based on Tweakers.net review findings:
# https://tweakers.net/reviews/13662/corsair-xeneon-edge-tof-idee-maar-dramatisch-uitgevoerd.html
#
# The factory settings prioritize brightness (365 cd/m²) over color accuracy.
# This script applies calibrated settings for better color reproduction (~255 cd/m²).
