Her polls go up when shes not seen in the public but they drop when she is seen have you noticed that? So imagine the 2.5 week long tour. I see her making a spike in interest as this is her 1st tour then dropping as the tour goes on because its so long. I personally dont think she will get much interest in the documentary as she will only talk about herself, her veil & wedding for like 2.5 seconds. She doesnt get a sit down interview like the other royals do.
