This is a very interesting thread and I thank the OP for starting it.

It seems there isn't a simple correlation between the raw data for each pixel and the chroma and luma data for that pixel, so when SPP calculates the chroma and luma data it adjusts the values, discarding data if necessary, before displaying the result.

It would be good if there was a setting in SPP that maximized data retention, producing a "negative" in TIFF.
