This was my feeling after seeing it too. Architects also love to see models and more tangible things, even printouts in my experience.

Offering a fully rendered environment sounds amazing but someone would have to do a lot lore work at the office before presenting it to the client because it would look less complete than simple foam models can.

It may be useful for investor presentations for really large projects (Saudis or UAE style projects), but again, those are pretty narrow audiences and so expensive that bespoke displays could be viable.
