What this LUT does

Measured from the file itself: it adds contrast (about 11% steeper through the midtones); pulls saturation down around 6%; leans warm shadows, warm highlights.

How this was measured: a 21-step neutral ramp and nine saturated probes are pushed through the lattice and compared with what went in. Contrast is the slope between 35% and 65% input; saturation is the mean change in distance from the grey axis; the cast is the direction a neutral input comes out at three heights. Rec.709 luma throughout — the same coefficients the previewer uses, so these numbers describe the image in the slider above.
