One possibility is to create your own private HDTV cable channel with test patterns by using the ZvBox 150, and then use your STB to tune to that channel.

Actually, you should be able to increase the brightness/luminance of the primaries/secondaries using the Samsung 6 axis CMS. On my Samsung A550, the scale is 0 to 100 with 50 being the default. So, to increase the brightness of a primary, increase it's number. To increase the brightness of a secondary, increase both contributing primaries equally. Also, it's important to remember that when you change any numbers relating to a color, you'll alter the overall luminance of that color. For example, if you want to move magenta toward red, you can do this by either decreasing it's blue component or increasing it's red component. The former approach will decrease the luminance of magenta a bit while the latter approach will increase the luminance of magenta some.
But you can't increase the saturation of a color - which does make logical sense if one assumes that the native primaries are the "most" saturated that the display can achieve. In other words, there is no way to make the display's native green, "greener." Even if it was possible, the interface doesn't allow it since the defaults for the non-contributing colors are 0. e.g. In the Samsung interface, to increase saturation of green, you would need to subtract red and blue equally but they are already at 0 by default thus you cannot lower them.
hope this helps,
