No, unfortunately not:

Calibrate a Display, Version 0.60.2
Author: Graeme W. Gill, licensed under the GPL
Diagnostic: Usage requested
usage: dispcal [options] outfile
 -v               Verbose mode
 -display displayname Choose X11 display name
 -d n                 Choose the display from the following list (default 1)
    ** No displays found **
 -c listno            Set communication port from the following list (default 1)
    1 = '/dev/ttyS0'
    2 = '/dev/ttyS1'
    3 = '/dev/ttyS2'
    4 = '/dev/ttyS3'
 -a                   Run instrument calibration first
 -r                   Report the current display calibration then exit
 -m                   Skip adjustment of the monitor controls
 -u [profile.icm]     Update previous calibration [update profile with new
calibration]
 -i 92|94|SO          Select target instrument
                      92 = DTP92, 94 = DTP94, SO = Spectrolino
 -q [vlmhu]           Quality - Very Low, Low, Medium (def), High, Ultra
 -y c|l               Display type, c = CRT, l = LCD
 -t [temp]            White Daylight locus target, optional target
temperaturee in deg. K (deflt.)
 -T [temp]            White Black Body locus target, optional target
temperaturee in deg. K
 -w x,y               Set the target white point as chromaticity coordinates
 -b bright            Set the target brightness in cd/m^2
 -g gamma             Set the target response curve gamma (Def. 2.2)
                      Use "-gl" for L*a*b* curve
                      Use "-gs" for sRGB curve
 -k factor            Amount to try and correct black point. Default is 1.0
 -e                   Run verify pass on final curves
 -E                   Run only verify pass on current display setup
 -p ho,vo,ss          Position test window and scale it
                      ho,vi: 0.0 = left/top, 0.5 = center, 1.0 =
right/bottom etc.
                      ss: 0.5 = half, 1.0 = normal, 2.0 = double etc.
 -n                   Don't set override redirect on test window
 -N                   Disable auto calibration of instrument
 -D                   Print debug diagnostics to stderr
 outfile              Base name for output .cal file
