To use the photograph analogy, if a person uses a typical 35mm camera a photo of a duck will have the same proportions and color gamut as a photo of an iPhone and have a similar tonal range and if the focal length of the lens is the same, the field of view will be the same.

The model is an instrument not the subject itself. A person cannot cook dinner in the kitchen of a blueprint.

But that is not how these models are constructed. They are from empirical data - they just tell you how many objects of a given size exist. The analogy is that the power spectra for the brain and the power spectra for the large scale structure are two different photographs (of actual things!) and look strikingly similar.

Viewed from five meters away, a photo of a duck and a photo of an iPhone may appear to be strikingly similar. The important differences depend on the level of granularity at which they are observed and the purpose for which they are observed.
