If I set my background image to a grey tone it becomes brown when the
.cal file is applied. I don't think it's the actual team that is grey,
especially considering the dell display shows it as grey and seems to
be well calibrated.

Both seem to show a gradient of brown.

$ dispcal -v -E -yl -d2
Setting up the instrument
(...)
Display type is LCD
Target white = native white point
Target white brightness = native brightness
Target black brightness = native brightness
Target advertised gamma = 2.400000
Commencing device verification
patch 6 of 6
Black = XYZ 0.48 0.50 0.87
Red = XYZ 34.63 20.47 4.45
Green = XYZ 30.25 51.18 12.69
Blue = XYZ 19.71 17.13 92.57
White = XYZ 91.43 96.62 111.93
Initial native brightness target = 96.618046 cd/m^2
Target white value is XYZ 91.426662 96.618046 111.933131
Adjusted target black XYZ 0.48 0.49 0.90, Lab 4.62 0.55 -4.53
Target black after min adjust: XYZ 0.480 0.494 0.897, Lab 4.617 0.548 -4.526
Gamma curve input offset = 0.000000, output offset = 0.005111, power = 2.432063
Total Iteration 3, Final Samples = 64 Final Repeat threshold = 0.600000
Doing verify pass with 100 sample points
patch 100 of 100
Verification results:
Brightness error = -0.037236 cd/m^2
White point error = 0.060846 deltaE
Maximum neutral error (@ 0.950471) = 1.738132 deltaE
Average neutral error = 0.942925 deltaE
Number of measurements taken = 100
The instrument can be removed from the screen.
