On a side note. What's up with the Spears & Munsil test disc. The contrast & brightness are always off with everything I've tried it with.
Again, that's something you need to check against your particular Display. Even Displays that claim to accept 10 or 12 sometimes only treat it as 8, or have peculiarities (i.e., bugs) in the way they display it. The test scene in "Ratatouille", Blu-ray, I alluded to can help in figuring this out.
But before you can even attempt to see such subtle differences, you need to get your calibration levels correct. Which brings us to your Spears & Munsil issue.The gray scale charts on Spears & Munsil, Blu-ray are ACCURATE. If you are having trouble getting Contrast and Brightness correct then something is wrong in your setup.
The OPPO 83 you are using puts out "reference" signals on the HDMI cable when set to its default value (0) Picture Adjustment settings. Set everything in Picture Adjustment on the 83 to 0.
Similarly, in the Anthem, leave the Video Source Adjust > Picture > Brightness/Contrast, etc., settings at their default values for that input from the OPPO.
Make all of your level adjustments using the controls IN YOUR DISPLAY.
In the first post of this thread you will find links to tutorial posts that may give you a leg up on getting things set up correctly. In particular, you need to start by picking the correct "Picture Mode" in your TV. See the Setup related posts included in that long list of tutorial post links.
There's also a whole forum here devoted to Display calibration, where you'll find sticky threads with tutorial information, and folks with helpful advice.
Also check the owner's thread for your model of Display for advice on any preliminary settings you need to make to make it POSSIBLE to adjust the Display properly. Things like turning off Automatic Gain or Contrast adjustments, or Flesh Tone "enhancement".
But trust me on this, the Spears & Munsil gray scale charts are correct, and the 83 renders those charts correctly, and the Anthem passes that along correctly.
By the way, there's a thread here at AVS run by the people who authored that disc, where they answer questions on how to use that disc. A Search should find it.
When people say they are having trouble getting Contrast and Brightness right, often there are one of two common problems. First, they've got the wrong Picture Mode set in their Display -- a mode that makes it impossible to calibrate the display correctly. Second, at some point in the video chain they are sending video in the RGB data format, and there is a mismatch between the two devices at either end of that cable as to which flavor of RGB is in use.
In the OPPO, these are RGB Video Level (the one you want) or RGB PC Level. In the Anthem, the one that matches with RGB Video Level is called Studio RGB. In your Display it could be called anything, but the setting will have only two choices. The one you want is where Black is given the value of 16 instead of 0. If you use YCbCr data format you won't have to worry about this.
This choice as to which flavor of RGB data will be sent and which flavor the receiving device expects has to be made MANUALLY in both devices. The HDMI handshake can determine automatically that RGB data format is in use, but it can NOT tell which flavor of RGB is in us. If there is a mismatch in the choices set in the two devices at either end of a cable, and if RGB data format is in use on that cable, then gray scale will be messed up.
