It looks that way to me. I fed a master 1920×1080 pattern from the qd780 to the tv via HDMI 1,then viewed it firstly in THX mode and secondly in cinema mode. The pattern has cropped circles on the four corners and top/bottom on the large circle in THX mode whilst cinema mode displays all the circles intact. I took a couple of pics to illustrate but the jpegs wouldn’t upload.
