**Do Holographic Screens eliminate the need of finding holographic dualities?**

There are various models in physics based on the famous holographic principle (https://en.wikipedia.org/wiki/Holographic_principle)

This does not always work since in these models we must find a correlation between two theories, one in nn Dimensions and the other one in n−1n−1 Dimensions, and such correlation does not always exist.

However, there is an "alternative" in holographic models, called "holographic screens" (https://arxiv.org/abs/hep-th/9906022) which eliminates the need of having a boundary in these models. This makes me think that we can represent any theory or model in nn Dimensions without the necessity of finding a correlation to a n−1n−1 Dimensional theory or model, but I would like to confirm it.

So, in summary, can we use Holographic Screens to make a "1 to 1" representation of a theory or model? I mean, can we use Holographic Screens to represent the same theory or model without changing nothing of it (without changing it dimensions or any of its properties)?
