Quote - Do you mean the preview of your scene looks the same? (It will  - no change - preview doesn't do falloff)

I have noticed that preview display does change to certain degree if spotlight is farther away.  It appears not to change if light is close to an object in question.

One thing I do notice is that when change the spotlight to say, inverse linear, all the infinite lights will then say that also.  There is no effect on them (because no degree of infinite, I suppose) except the label.
