Apple TV color Calibration does not works with Projector (Home Theatre). Please resolve ASAP.

I have an Apple TV HD version, I am able to connect my iphone to tv for the calibration process but when I bring my iphone close to the projector screen, it won’t work. As on the “blue picture” outlined under the iPhone shape, my iphone’s shadow falls (as a result of the projector light being blocked by my phone).

Please resolve the issue Apple.
