If you watch ycbcr content (blu-ray, dvd) by converting to rgb and you have the tv set to hdmi low, what happens is that the standard space of 16-235 is being extended into 0-255, which means that if you leave the brightness setting alone you are now clipping near black content which creates the impression of depth but at the cost of shadow detail. If you correct your brightness setting IT'S STILL WRONG! Why? Video uses below black information and above white information as well, you set brightness to clip below black anyway, but when you extend the standard levels you are now clipping the headroom for superwhite. Which is important and should not be clipped.
The correct thing to do is make sure that white above white (known on the ps3 as superwhite) is passed, use standard video levels, and output as ycbcr, and not rgb. When that happens the hdmi option will be grayed out as it should be.
Yes, but here's what happened with my 590 and PS3. We had all the settings the same as you described (on the PS3 and the TV) with the HDMI Black Level set to Normal. Calibrated the set and took measurements. At the time you couldn't change the HDMI Black Level to Low anyway since it was greyed out in the menu, which is appropriate since it should not be applicable while the TV is receiving a ycbcr signal. He then went to the PS3's XMB screen, which I believe uses RGB, and the HDMI Black Level menu option was now selectable. He changed it to Low. He then re-activated the disc and ran some test screens and did a full set of measurements again, using two different measuring devices and ran the full calibration report again. Black levels improved substantially and every other setting was unaffected. No black crush, etc. Interestingly, the HDMI Black Level was not selectable again because it was a ycbcr signal, even though the black level was noticeably impacted by the change.
