Thank you so much for the suggestion and efforts in moving the pics! Yes, they are all pics of the same plant.
It was discussed a few years ago that this plant is not 'Ghosty' and the pics were moved to G. para. I've always thought the leaves of my plant were more chunky than other pics of that species, but never have put any in a different location to see how that might alter the appearance.
For reference, here is the label from when I bought it, 3/20/13. This company is well known for their great selection of cute little plants, but slightly-off labels. Maybe at some point it will be determined exactly what they were selling with this label at the time.
