Is the reason why SPD is an infinite-dimensional signal because SPD doesn't just represent the visible part of the spectrum?

Yes. Since values of wavelength could be infinitely many. They are not necessarily integers

If we had a fourth cone, but still the same range of viewable colors, would the dimensionality of the signal still be 3? I think the fourth cone would not be linearly independent.
