I worry about all the non knowledgeable readers. Those that see spec's for a
10-bit display vs. a 12 bit one and assume by that spec alone, the 12-bit unit
is superior.
More is better right? But then that's why marketing exists, for the slew of
mostly non knowledgeable readers.
I also somewhat worry about those that believe R0/G255/B0 in ProPhoto RGB is a
color. It's a color number, that's for sure.
