To bring up an example from current WCAG 2.0, when talking about color 
contrast for instance, the SC doesn't talk about contrast "as measured 
on the screen" - as doing that would be outside of a content author's 
control, as they can't query/account for differences in display/screen 
quality, brightness/contrast settings, color profile 
calibration/miscalibration of the display, etc.

In this situation as well, the responsibility of having a device with a 
display that is actually "reasonably" (for whatever definition of 
"reasonable") well calibrated lies with the manufacturer to one extent, 
and with the user to ensure whatever settings they have access to are 
set to their particular needs and requirements. At the risk of stating 
the obvious, It's the interplay of responsibilities between user 
agent/device manufacturers, web content creators, and indeed users - the 
onus can't be shifted just to content authors (particularly for things 
they have no direct influence over).
