The gamma LUT refactor (#14123) moved gamma correction to after the constant_brightness balancing formula (max/sum ratio). This broke constant_brightness because gamma is nonlinear and does not commute with the ratio calculation, causing a severe brightness dip at mid-range color temperatures. Fix by applying gamma to individual CW/WW/brightness values before the constant_brightness formula, restoring the original behavior where total power output remains constant across all color temperatures. Closes #15040
