Linear light questions
#1
I have some questions about linear workspace.

I followed the instructions here and determined that Gimp 2.10 does indeed use linear calculations:

That's great!  I already knew this, sort of, but I have some issues understanding what is going on.

These tests work in both perceptual sRGB and Linear light.  What happens when I change the precision to 'linear light'?  Is it something that becomes embedded in any file I export?  I have also noticed that bit depth makes no difference, so why would I need to change it to higher than 8 bits if I just want correct linear maths?

Why does every guide I read about linear light insist that more than 8 bits are needed if I want to use linear light calculations?  Obviously this is not a strict requirement if Gimp can do linear calculations in perceptual sRGB and 8 bit.
