From a Crawley article that I've posted here previously, talking about the new (as it was then) Delta 400 a comment about four emulsions being in D3200 if I'm reading it correctly:

With the launch of Delta 3200 last year, Ilford came up with a
solution to the problem, evolved from 100 Delta. The same
principle is applied in the new Delta 400 reviewed here. In fact it
harks back to traditional know-how but in an updated guise. Delta
3200 is a bi-pack, and each of the two layers is made up of two
emulsions, four in all, of which three are new. The high-tech
halide crystals have a silver iodide rich core around which is the
bromide shell and sensitisers. The interfacing of the iodide rich
core with the bromide shell creates a larger number of possible
latent image centres in the shell to trap the incident light. So there
is enhanced sensitivity and pushability.
