Having also spent a long time in actual holography, I would agree with your assessment generally and your catalog of different "holographic" techniques.
I might quibble with lenticular displays, since they have a name that predates holography.
In the ideal world, a larger umbrella term would have emerged. "Autostereoscopic" describes any display that provides different views without glasses, but that typically suggests discrete views.
"Plenogram" would have been reasonable following Adelson and Bergen's plenoptic function, but that didn't and won't happen.
"Hologram" now basically means a sufficiently advanced three-dimensional display in popular culture. And that even leaves of other real holograms, such as the ones used for non-destructive testing.
