I have been inadvertant and completed deliberate IMC aborts from the hover (day and night) - the initial part has to be about flying the aircraft as accurately as possible to get above safety altitude and that comes down to basic instrument skills.
Knowing where the high ground is and any obstacles (masts etc) is useful and that is what the synvis would give you but, too much information (however nicely displayed), can give sensory overload and distract you from what you really need to be concentrating on.
When the leans get you, it is not about how nice the display is, it is about how disciplined you are to believe your instruments, and that can be tricky if you don't practice regularly.
