Not really. I stayed at the Venetian last year, and my my room didn’t include the sphere view in either the features or as an upcharge. (The sphere is “part of” the Venetian, so they’d be the most likely to advertise rooms with a view.) Their room is quite a bit further than mine was. They may have paid for the strip view, but without specific advertising they probably would not be able to tell ahead of time if they’d have LOS on the sphere.
