1886 vs 2.4 LUT

anevard · 2026-09-11T17:38:12+0000

I am wondering if it is ever appropriate to use 1886 as a LUT source vs 709 2.4G for a projector that is profiled with a black level of around 0.005 NITs or higher? Projector destination profile is native gamut and native 2.2 gamma. Sources would be blu-ray disc or SDR streaming.

		As we have explained in the website, BT1886 is a flawed concept. https://lightillusion.com/issues_bt1886.html Avoid. Steve Steve Shaw Mob Boss at Light Illusion
