Should it be possible to use camera and Orientator on iPhone the same as an iPad?

For the first time in a very long time I have a real call for using the Orientator while air playing the iPhones camera. While the iPad2 works fine, it’s a little large for this purpose. Should I be able to see the camera on the iPhone screen or just the Orientator’s green screen with al the data readings? Would be good to know either way, Thanks. MBP 2014 Retina, OSX 10.10.2. iPhone 5, IPhone 6, iPad2 all iOs 8.0.2.

I have to admit I don’t really understand what you are trying to achieve, can you please explain further?
