What have open papers measured about colour-rendition limits of RGB LED volumes for lit subjects (skin, clothing), and how far do 3x3 corrections get?

Two open papers attribute LED-volume colour errors to narrow-band RGB emission seen through camera sensitivities (lighter skin pinker); a 3x3 pre-correction of panel content plus camera post-correction (and black-level subtraction for 4-10% panel albedo) improves skin and orange/yellow materials, but residual errors remain (sodium-vapour light; saturated reds and greens) that no 3x3 matrix can remove. Neither tests RGBW/RGBCA panels or diverse skin tones.
