A first-hand ASC test of Kodak film and an Alexa 35 against an LED wall (D65 native, content at 3200 K and 5600 K) reports that light meters misread narrow-band LED light so a digital camera and calibrated monitor stay necessary, that wall colour must be calibrated to the shooting camera's colour matrix, and that cameras must sync to panel refresh (genlock for digital; a sync box for film).
