There are many many people who get their displays ISF calibrated. The
incorporation of ISF tuning is a major selling point for high end displays
(actually, for anything of quality). I, and many others, already have the
hardware for ICC profile generation (and could always purchase software such
as Colorfacts - does Spyder TV have a software only version that will run
with a range of spectros?). My understanding thus far is that broadcasting
standards incorporate colour space specifications. What's missing is proper
colour profiling of the display. (And wouldn't anyone running all video
sources through a video processor in affect only have to profile for one
source...) It seems to me that ISF calibration is a halfway house to proper
colour management. But then I've a lot of info to continue reading....
