1.07 billion colours? How can the part have 1.07 billion colours if the colour depth of the display is only 8 bits? 8 bits per colour result in (256x256x256=) 16'777'216, i.e. ~16 million colours. Only 10 bit resolution (i.e. 1024x1024x1024) would result in said 1.07 billion colours. colours.

You can't know everything, you'll find an answer here:

Panel colour depth: 10 bit (8 bit + FRC)
Most common are the panels that have 6, 8 and 10 bits for each of the RGB components of the pixel, ensuring 18-, 24- and 30-bit colours respectively.

FRC
Frame rate control (FRC) is a process that allows pixels to display multiple shades of colour. The fast cycle-like change of different colour nuances creates the deceptive perception of an intermediate nuance. For example, FRC makes it possible for a 6-bit matrix to visualise the 16.7 million colours typical of the 8-bit matrix instead of the standard 262200 such for it. Various FRC algorithms exist.

Colours: 1073741824 colours, 30 bits.
The maximum number of colours that the display can reproduce depends on the type of panel used and the use of technologies such as FRC that increase the number of colour nuances.
