Does the iTunes Store TV shows listings show a complete listing for the category?

My example. I recently purchased the TV shows Broadchurch from iTunes Store, and it's from the ITV television network section. When I browsed that same section today, the program Broadchurch did not show up on the screen listings. I had chosen list by name, assuming that this would give a complete list. However, if I type Broadchurch in the Seach box, it is still available for purchase.

This suggests that the on-screen listing is a pre-selected list and not a complete list. Is this true? Am I missing something?
