Yeah - they build the model from photos, but they limit the movement to the spots in the model where the photo was taken, then show you the photo. It's the same thing Microsoft Photosynth did a few years ago.
Saying "Our model quality has changed a lot in 2 years as well." and then presenting the 2014 photo is pretty sketchy.
An accurate comparison would be viewing the model from the same position as the photo, using the model, not the photo. Or allowing arbitrary angles - I bet if you look under the machines on the front desk on the actual model, they've melted into the desk a little bit.
Or - I do understand the quality is not there yet - say 'Our viewing experience has changed a lot in 2 years as well.' and show the old viewer and new 2D/3D combined viewer.
You could bring in the entire .object into Unreal Engine first person template right now. Having whole rooms as models (rather than BSP brushes) is actually pretty common now. You might have to fix lightmaps and maybe make a low poly version first.
