While the various ∆E color difference metrics, specifically ∆E00, have served well for assessing perceptual color differences in standard dynamic range (SDR), the introduction of high dynamic range (HDR) and wide color gamut (WCG) technology raised the question of whether these metrics were still applicable with these new capabilities.
Color science expert Charles Poynton and SpectraCal software developer Joel Barsotti provide an explanation of the varying methods used to interpolate 3D LUTs for the calibration of video displays. This paper was presented at IBC 2014 in Amsterdam.

Since the International Telecommunication Union (ITU) adopted BT.1886 as the recommended gamma function for flat panel displays used in HDTV studio production in 2011, some confusion has arisen over the usefulness of the function, as well as its application in the field.

How Long is Enough?
A meter’s viewing angle is not really something we need to be concerned about when dealing with transmissive illuminate displays, like flat-screen TVs, since the meter is typically either in direct contact with the screen or very near it.
