(Left) Noting that the uncompensated black offset
for the blue channel is negative, a correspondingly
equivalent positive setting is applied using the blue
channel Black offset control (in this example,
adjusting the Black offset from unity to 5.0 provides
compensation).

(Right) Noting that the uncompensated blue Gain
exceeds ideal 100% level, a correspondingly
smaller gain percentage setting is applied using the
blue channel Gain control until the gain is observed
as 100% (in this example, adjusting blue Gain from
unity to 87.5% provides compensation).

(Left) Noting that the uncompensated blue Gamma curve
indicates gamma factor is less than ideal 1.000, a
correspondingly greater numeric gamma factor is applied using
the blue channel Gamma control until the blue gamma function is
observed as linear (in this example, adjusting blue Gamma from
unity to 3.333 provides compensation).

(Left) Compensated Offset, Gain, and Gamma
are now symmetrical across all three color
channels, resulting in proper monitor
appearance in the OTA feed.
