Ultra-short throw has to reject light
Light arrives from the bottom edge. A plain screen throws the ceiling fixtures back at your eyes. A CBSP-class stack keeps light that did not come from the host out of the picture, so a daylit living room can still watch. This is a requirement, not an upgrade.
Floor-rising
The screen rises from the floor or the cabinet. The wall stays clean. For a living room that can take a floor cabinet or an integrated run — the typical way an invisible cinema appears. Common sizes 92 to 150 inches.

Ceiling-recessed
The screen lives in the soffit and only exists when it drops. The floor stays free; the wall can still hold a painting. It needs a prepared cavity. An old room with no soffit will feel it.

Motorized drop-down
A box on the wall or the cabinet top — the smallest change, for a rental or a light renovation. It looks a little less like “the wall is empty”, but the optical layer is still cut for ultra-short throw.
