What is the point of having 16 bit colour if a computer monitor can only display 8 bit colour? How do you edit 16 bit colour when you can only see 8 bit?

Do publishers use highly advance monitors or
super-knowledgeable graphics professionals who know how things will
turn out even if they can't preview them?

Precision - so that when you adjust the levels in the image, you still
have more than enough bits.

One of the reasons lies in the lack of computational accuracy during
editing, that rears its ugly head as a the "combed histogram":

Same issues that raw files help with. Dark blue and/or red/yellow sunset
skies with gradual transitions are the worst. If the initial exposure
and lighting is good, there's no benefit.

There are always trade-offs.

Thank those who decided to use RGB for monitors and CMYK for printing.

go learn about additive and subtractive colour.

What do you think they should have chosen?
