See how you call it yourself "data stage settings" and not "prototype stage settings" as it's technically called, by the same abuse of language, I would call the "runtime settings" the "control stage settings" since it's more explicit what is meant by that, because when I said "at runtime" (in the context of my sentence), I only meant it's a mod setting that's user-exposed at runtime, implying it should have been available to you, the user of said mod, if you looked into any of its settings, which relates directly to you saying you "don't use this mod for the LUT effects", but haven't really looked into whether it allows you to ignore them to begin with.
Also it should be obvious that LUTs defines are data stage, and can't be controlled by the runtime API.
