If we’re able to create the illusion of the 3rd dimension on our 2-dimensional screens, why aren’t we able to simulate/create the illusion of the 4th dimension in our 3-dimensional world?

Only “3d” is “real” or perceptible. A dot on a page is still 3d. It’s ink, it has thickness. But it’s easy for us to imagine a dot without dimensions. It’s practically nothing, just position information (its coordinates). But from this we can understand that “one dimensional” is a theoretical thing. Not “real”. Just like numbers and maths. We use them but they don’t exist physically.
The same goes for a 2d drawing. Its bi-dimensionality is theoretical. We just ignore the existence of the 3rd dimension.
We can imagine the 4th dimension in the same theoretical way but that doesn’t mean it actually physically exists. If it did we could never experience it just like we can never experience being 2d. Because none of these are real tangible things. They’re words.
