jmccrossan-fox has just created a new issue for https://github.com/w3c/ttml2: == Add informative note to tts:luminanceGain that tts:luminanceGain is not relative to graphics white of the display == Currently the definition of luminanceGain states: _"The tts:luminanceGain attribute is used to specify the absolute luminance of a region when its presentation requires a greater dynamic range than that provided by the [SRGB] color space, and when that presentation requires an absolute luminance value."_ To provide further clarity, consider adding an informative note to the above to advise that when tts:luminanceGain is applied during presentation it defines an absolute color & brightness, and it does not reflect a luminance level which is in relation to the graphics white of the display.
