I think the mistake is equating a "brighter" picture with a "better" picture. All modern LED/LCD sets are more than bright enough for home viewing. Having the brightest possible picture, I suppose, is good if you like an unnatural, washed-out looking image that blows out highlights and fine details in HD images.
