I suspect "perfect uniformity" is too much to expect from any large edge lot set, however, my replacement set (79") is truly excellent with no noticeable edge bleed. I am withholding judgment on black levels until properly adjusted. That should occur in a couple of weeks. Our room does have some ambient light, however, and at present we are very pleased with the picture quality. I don't notice any uniformity issues in watching movies and even when all black withnthe Oppo logo going around the screen I don't notice any significant uniformity issues.
