EXP stands for Expanded. These versions apply a slightly broader tonal curve and lesser highlight or shadow roll-off compared to the standard variation. This gives you a slightly more expressive and stylized interpretation of the stock, particularly useful in stylized, narrative, or commercial work where more character is desired. It’s not a dramatic change but can help footage feel more “expanded” without needing extra grading steps.

In the left, you can see that the highs & the lows are a little expanded.
