I get what you mean, like there’s definitely some stuff you can just look at a picture of it on the internet, but I guess for others it’s about the sense of space, connection, grouping, narrative, context etc that’s present with a well put together Museum or Gallery display.
Without all that, you’ve just got a car boot sale of random things - wheras the text, maps, illustrations, audio, video or 3d recreations etc that sits alongside - or simply the placement of things next to one another, or following through the room in a particular order is what really makes that stuff interesting.
