You should always optimize the screen for faithfulness and then filter in software for readability. That way you can easily turn the filter on/off.
Just like I've got to have filters that force websites not to use too contrasty colors.

"Screen configuration" means more things. You can optimize for readability, or you can optimize for faithfulness (and more). You should switch according to use.
