Inverts the image by inverting the channel values.
\[f(x) = 1-x\]White becomes black and vice versa. Hues are rotated 180° – red becomes cyan, green becomes magenta and blue becomes yellow.

Point reflection / rotation of the colour wheel without inversion of the Lightness.

This inverts the image but keeps the hue.
It combines both operations of Channel Inversion and Hue Inversion in order to avoid the rotation of the colour wheel.
