But that's what it's about, more or less: https://en.wikipedia.org/wiki/Proprietary_software. While exact definitions of open, closed and proprietary software vary, no mainstream definition is related to "specific to an OS". Software can be single/multiplatform and it can be FOSS/proprietary, and those two axes are independent.

If Apple retains some "secret magic sauce", sure. However, on a level field, with full access to the hardware for everyone who asks, who can say?
