What is a proper situation for await Task.StartNew(() => ...)?

I was wondering whether someone could help me figure out a proper use for code like 

var result = await Task.StartNew(() => ...);

or 

var result = await Task<T>.StartNew(() => ...);

From what I understand, it would never make sense to have simply

await Task.StartNew(() => ...);

or 

await Task<T>.StartNew(() => ...);

because if you don't need the result then you might as well fire-and-forget with

Task.StartNew(() => ...)

or 

Task.StartNew<T>(() => ...)

which which is like 

Thread A | ----- Stuff before the Task.StartNew ---- | ---- Stuff after the Task.StartNew ------------------
Thread B | ------------ ??? ------------------------ | The () => .... inside the Task.StartNew -------------

Can someone provide me with a real-life example of when this would be useful?

None!

Unless you know exactly what and why you're doing it, you should never use Task.Factory.StartNew or Task<T>.Factory.StartNew with async-await.

Not awaitng on the result of a task does not mean that you don't care about the result value. It means you don't care if it completes with success or even if it completes.
