Most LUT packs overlay color on top of whatever your camera renders. gradedlooks builds from the sensor up. ICC profiles normalize your RAW first, then the look sits on a truthful foundation. The difference is visible. And measurable.

A lookup table takes an input color value and maps it to an output. Blind to your sensor. Applied on top of whatever camera rendering your software happens to produce.
Change cameras, A7IV to a GFX 100S, and the same LUT produces different results. Because the input changed. The LUT didn't know that.
Most “cinematic” packs are LUTs. Appealing in screenshots. Inconsistent in real shoots.
ICC profiles characterize the actual spectral response of your sensor at the RAW level. Capture One reads this to normalize the RAW into a scene-referred state, before any creative layer is applied.
Every graded look is authored on top of an ICC foundation. The look targets calibrated data, not a sensor lottery.
Switch cameras. Switch lighting. The look adapts because the foundation is solid.
