15/16 bit is measured in thousands of colours. 24/32 bit is Millions of colours, thats why 32bit looks best and theres no reason to use anything less on todays pcs

Who told you tft's only display 16 bit? You've been BS'd mate.
Just for the record
16 bit = 65,536 colours
32 bit = 4,294,967,296
Well, at least that's how it should be.

Quite an informative (if a little dry) article:
Here
Read "the colour depth issue", about 1/3 way down. Should clear everything up!

its 24bit + 8bit, the 8-bit being the available greys hence 32-bit.
technicaly speeking its 16.7 million collours, the rest is greys.
A 10-bit implementation isnt viable at the consumer level, it would achieve 30-bit colour plus another 10-bits for the greys.

To work out the number of colours available for a given bit-per-pixel count, raise 2 to the power of bitdepth.
16bits = 2^16: 65,536 colours
24bits = 2^24: 16,777,216 colours (16.7 million)
32bits = 24bits with 8bits of alpha channel information (256 levels).
