Detect applied fx in ExtendScript

[MARK3662717834h1]

Is there a way to detect if an effect has been applied to video or audio clips using the ExtendScript API? After some investigation stepping through code I'm not finding any obvious places to look. Essentially all I need is the equivalent of "seeing" that the fx indicator is illuminated or not for a given clip.

Yes; ExtendScript can iterate across the component chain of a trackItem. If that component chain is longer than 2 items, there's an effect applied; relevant example code here.
