Banding is that annoying color gradient you see sometimes in dark scenes.
On the left is 8 bit and on the right is 10 bit.
Hold up. That entire image is 8-bit. It's a JPEG image. JPEG can't encode more than 8 bits per channel. Nor can most displays, including mine, display more than 8 bits per channel. And yet the left half of your image exhibits far worse banding than the right half.
The left half looks more like 5 bits per channel rather than 8. You'd see that kind of banding in gradients back in the days of Windows 3.1, when 16-bit color was common. (16-bit color uses 5 bits each for red and blue, and 6 bits for green.)
It's an exaggerated example to demonstrate the concept of banding more clearly, not a technical breakdown.
Then it should be marked as such. It's highly misleading to anyone who doesn't know better. Again, you're demonstrating the difference between 5-bit and 8-bit color, not the difference between 8-bit and 10-bit color.
The purpose of the comment is to demonstrate banding. The only reason I marked it in bits is to show how banding can be reduced in video encodes by increasing the bit depth, not the specifics depths itself, it's not a technical write-up.
