It tells you nothing really. There are probably a hundred or more labs in the US alone still processing E6, some capable of large volumes. (A single lab was capable of keeping up with Kodachrome processing worldwide in its final days.) This doesn't take into account the people who are processing E6 themselves, and still others who are cross-processing it.
Nothing? I dont think so. If there were E6 labs on every street corner it would tell you that there popularity of that film was sky high. Watching labs close down the past few decades informs the observer that it's not economically viable to base a business on developing E6 film. The number of labs that process E6 diminishes each and every year.
That tells me something about E6 film, but perhaps nothing to you.
