So in the universe with only bosons (so Pauli principle doesn’t apply), everything is the Same?
When I imagine a room full of photons, I see a lot of things that can be Different. For example, the coordinates of photons, wavelength, polarization, their number.
Or are you saying that Pauli principle is sufficient, but not necessary?
This strikes me as a question with a concrete and unambiguous answer: difference exists because of the Pauli Exclusion Principle.

Nothing more is required.
