Question: are 4k discs the same as blu ray?
Answer: 4K Blu-ray These are standard Blu-ray discs that have been scaled down from a 4K picture. They offer a wider range of color, but it is not the same as a 4k Ultra HD Image. A 4K Ultra HD Blu-ray disc has a much higher capacity than a standard Blu-ray disc which allows it to store a movie with Ultra HD resolution.
