When it comes to image quality, a 4K Blu-ray movie generally looks better than a 1080p Blu-ray movie when played on a 1080p TV. Even though the 1080p TV is not capable of displaying the full 4K resolution, the higher bitrate and increased color depth of the 4K Blu-ray disc result in a more detailed and vibrant image compared to the 1080p Blu-ray. The extra data and bandwidth of the 4K format allows for better representation of shadows, highlights, and a wider range of colors, leading to an overall more visually impressive experience. While the resolution may not be as high as on a 4K display, the improved image quality of the 4K Blu-ray is often noticeable and preferred over the 1080p Blu-ray counterpart when viewed on a 1080p TV.
