 +===== Expected results =====
 +   * Gamma \(1.0\) is an identity gamma, that produces a LUT of a linear set of incremental values with one-to-one correspondence between input and output
 +   * Image doesn't get washed out too much when Gamma is increased (within the \(1.0\)-\(2.5\) range)
 +   * Slight hue drift is expected, but not to be an excessive one at extreme Gamma values
 +   * LUT table for a given Gamma should match the one produced by the [[https://toolbox.sub2r.com/sub2r-tb-gamma.html|online tool]]
