What you are doing is calibrating the SYSTEM of the TV and the BluRay to provide a calibrated signal on that input (to the receiver and with that disc). It will not necessarily be correct for other inputs. It might not be totally correct for other discs if the signal on that disc was incorrectly mastered.
Fortunately, the common calibration discs are carefully mastered to provide a correct signal. In addition, since the signal is digital, the only analog section in that path is in the TV, and the signal will be correct for the BluRay player.
Now, when you add the 722 to the mix, you are adding the judgement of the engineers at the upliink center to the equation. I am assuming you are using an HDMI connection from the 722. This is also digital and no conversion or correction takes place. Assuming that the uplink engineer is monitoring and feeding a correct SMPTE calibrated image, you will have something as closely calibrated as you can reasonably expect. Again, the only analog path is within the TV.
If you are using component connections there could be errors added in the analog conversion in both the 722 and the TV. Which is one of several reasons you should use HDMI.
