I have noticed similarities in some textures

The Bedrock Texture from Minecraft and the Texture when you haven't unlocked a cup or haven't unlocked maps looks really similar, now I can't unsee it anymore...

It initially looks similar, but on closer inspection, the two are very different. The Ring Racers TV static texture uses more black in its image than the MineCraft Bedrock texture does. There is also the presence of an off-white color in the static image that the bedrock image doesn't have. Finally, putting the two textures side-by-side (and not at an angle like the bedrock cube image) reveals that they both use different patterns.
The suggested identical appearance is likely due to the nature of the TV-static look that both textures use, and that both textures are very small in size for optimization purposes.
