This would have been nice if code was included, but I did not see it. It is just the statistics of the specific Kodim dataset, that was once published on a Photodisc.

Use cases for this? Maybe to validate you own statistics computation?

The Kodim dataset is pretty useless nowadays. If you build an algorithm that runs on this dataset (or the Lena image) it will be pretty bad on other images. Think of data dependent things like compression, segmentation, inpainting or such. The specific characteristics of these "small" images are unlike a cellphone Jpeg or DSLR raw.
