That makes no sense at all. Every AVR out there has the ability to calibrate a room to whatever speaker brand you choose using the feed back from test tones and microphones, which is something trueplay could do. When a manufacturer provides a profile per speaker you load it in and no calibration is needed.
AVR calibration just basically sets the distance and levels of the speakers relative to the listening area. Key for timing and sound levels for multi-channel.
Trueplay is more like a DSP amp like a Sonance or AudioControl that used the profiles of particular speakers to tune the sound and EQ based on the room environment based on the performance curves for that particular speaker.
