For some reason if I use the Black Clipping pattern the near black bars (1% up to 8%) show up as solid colors (Red, Green, Blue). What's weird is near black window patterns all appear normal except 3% black is tinted dark red. I can also see faint colored near black lines playing the grayscale ramp pattern on the Xbox as well.
If I play your HDR patterns off my USB stick directly from my LG TV using the same picture settings these colored near black issues don't show up. Trying to narrow it down to a possible encoding issue or something weird in how the Xbox handles near black.
Just hooked the Xbox directly to the LG and reset all picture settings (including my service menu adjustments). Was still getting the colored near black issue though I noticed it was lesser on HDR Bright and even lesser on HDR Vivid. Besides Color Temp the big difference between the three HDR modes is the Color setting (Standard is 55, Bright is 60, Vivid is 70).
So I set the LG to HDR Standard and played with the Color setting. Going above 55 does nothing. But as soon as I went from 50 to 49 there was an immediate change to near black: all the bars that were colored switched to normal gray shades. And the pattern itself actually got slightly brighter (more near black detail). It was literally like breaking a wall. Absolutely no change from 55 down to 50. But as soon as I hit 49 everything looked normal.
It still seems like this is strictly an issue with my Xbox One S as playing your patterns off USB on my LG has none of these issues. Going to redo my calibration with Color of 49 and see what happens. Maybe when my Xbox One X arrives it won't have this issue.
- with Xbox One S hooked directly to my LG near black clipping patterns (and 3% near black IRE) have obvious color tint issues even with all picture settings on default
- tried all possible Xbox One S setting combinations but nothing fixed it
- playing the same patterns directly off the LG via USB using the same settings does not have this issue
- I found that adjusting Color to 49 for HDR Standard fixes the color shift issue when playing back on the Xbox
- Masciola tried to replicate this issue on his own Xbox One S but black clipping patterns displayed normally for him
I'm chalking this up to a fluke with my specific Xbox playback (hardware issue I'd assume) and hoping the Xbox One X I have ordered will fix it.
In the mean time I'm going to redo my HDR Standard calibration using Color of 49 and see if I can alleviate any negative affects this will have on Color calibration.
