Color Depth Test - 8bit vs 10bit vs 12bit

[OpenSource Ghost]

Are there patterns that can test 8bit vs 10bit vs 12bit color depth on a monitor to see if the monitor supports it correctly? There is supposed to be one that includes banding in 8bit but does not in 10bit. I can't find one like that.

The test patterns need to be in motion to better show the posterization effect. So you need a video to show it.

There is a test footage in Spears Munsil UHDHDR Benchmark displaying 8bit vs 10bit but you need to buy the disc to see the video.

Clearly visible differences on a LG42.

They are all 8bit in this screenshot format.

The picture is small so you don't see enough posterization.

If you see the 10 bit footage the upper box has 256 shades against lower box that has 1024 shades

Hmm maybe I saw what I wished to see.

What you see on the picture has only about 40 shades on the upper box. 200 shades on the lower box. 40-shade color is not even 6bit.
