I gather that modern simulators are considered to be training tools, so I would assume that a no hydrauic flight has been modelled, otherwise we wouldn't have been able to do so...
Nope, sorry. Modern full flight simulators are indeed training tools, and as such are intended to enable teaching of the various approved or recommended procedures, normal, abnormal and emergency.

If it's not in the flight manual, there is no expectation you'll be trained on it, and therefore no-one's going to waste time fine tuning the sim for a case that "doesn't exist".

The sim may also not be tuned for various combinations of failures; it may be representative, or it may not, depending on whether the failures interact in interesting ways or not. There's a set of generic validation tests for a sim, and there may be additional ones based on a specific training regime, but anything outside of that is rather nebulous.
