I just ran some tests. Just to be clear, this should only apply to a 6 or 7 series. 8 and 9 I recall being correct, but it is easy for anyone to verify my results. This is also for SDR, not HDR. HDR is fine on the 7 series.
I am currently in technicolor expert mode and have gamma set to BT.1886. In other modes, the bars will appear even more different (error). Dynamic contrast is off and edge enhancer is on (on is the off position on the 7 series)
1. Put up some SMPTE bars. I am using the SMPTE bars from the 2nd edition disc since they are HD resolution and 709. Wanted to eliminate UHD being an issue. (EDIT:
I did go back to the UHD HDR version and verify things match between the 2nd edition and UHD HDR edition when looking at the SDR BT.709 bars. Just wanted to confirm resolution or disc format was not the cause.)
2. Go to Expert Controls -> Colour Filter and set to green.
If SDR BT.709 color decoding is correct, then you should see what looks like one big massive green bar. Four of the bars turn green and should all match in level.
At default settings, you see one green, followed by a lighter green, followed by two greens. So you can see three different levels of green.
If you go to Expert Controls -> Colour Gamut and change it to Wide, the three green levels become one, so all four bars match. More importantly, if you go to our Color and Tint Green Only bars on the 2nd edition, the right half is green and the left half is black.
If you don't have the 2nd edition and do have the UHD HDR edition, then go to color and tint bars in SDR BT.709. In blue only mode, the left has colors leaking through instead of being black in default. When you change to Wide, the left half becomes black. HD color bars under SDR BT.709 will let you verify the four bars are green or not.
SDR BT.709 -> Setup -> Color and Tint for the blue only version of our color and tint bars
SDR BT.709 -> Evaluation -> HD Color Bars for the SMPTE style HD color bars
Just in case you have no idea what I am talking about by left and right half or left half turning black vs. showing color, here is our article
that explains it. It is how you know the color filter or blue only mode is working correctly.
Just for the fun of it, I tried using extended mode and setting color to 43 and 46 and they are way off. I had to actually set tint to G19 for tint to be correct, but then there was one green bar that stands WAY out when looking at the SMPTE / HD color bars in green only mode.
