Sheep's wool does not visually show the appropriate color

What I expected to happen was:
Sheep's wool to show the appropriate color when either naturally a different color or dyed

What actually happened was:

The wool color remains white (visually)

Steps to Reproduce:
1. Spawn in a sheep
2. Dye it any color
3. Notice that the wool color doesn't visually change
4. For a visual reference see the attached video

Edit by 576874: to better describe the overall issue

Original: I tried out the Wololo easteregg, and found out that sheep stay graphically white when I colour them. But mechanics-wise they changed colour because the Evoker or what he's called changed the sheep, but it was still white. So only a graphical issue. Huawei P9 lite
