I believe yes, irrespective of whether these are true holograms or using lenticular screens.
I could not find more details on the technology (beyond the basics that I already know).
Using a very large number of pixels is required to make good light-field displays. The high pixel density mentioned is reachable if the high DPI resolutions of smartphones is applied to a large screen display.
The challenge of refreshing the pixels is handled by having large number of electronic cards driving each section of the display (as seen diagrammatically on their website), which is perhaps where the high cost is.
I could not find if there is a lenticular screen somewhere in the display stack or not; my best guess is that it should be there.
