Logically, they should offer the same fare as Cambridge Station would
sell for a journey heading the other way, i.e. Cambridge to Heathrow

Is it always true that fares from A to B are the same as from B to A?
I've never been sure that the railway system has even such basic logic
built in.

Railcard discounts *should* be available, as they've been available on
through fares *from* National Rail stations to LU Zones for some time.

Every time I've asked, LU ticket offices have told me that NSE Network
Card discounts aren't available - essentially because their ticket
machines don't have the right programming.
