Hello Phil,
It was referring to black/white levels. This may not be a LUT related thing.
LUT has been implemented but not enabled by default because of some issues on some specific pixel clock ranges (and most people don’t have a clue what ‘pixel clock’ means or how to get it). If you have some missing grey scales, I think this maybe a bug we’ve since identified. The fix isn’t released yet, but we could get you a development build to make sure it fixes it for you as well, unless it’s LUT related.
Here’s how to enable LUT for calibration:
