Shout 4K (GKIDS)

Japan 4K Blu-ray is not english-friendly, but it does have drastically improved visuals over all the BDs, including plenty of grain and correct colors for the first time. The 2024 Italy Blu-ray did make most of the same improvements because it used the same master, but the 4K Blu-ray still knocks it out of the park https://slow.pics/c/gJ0nYfkv
