I guess your point is to try to find out whether the vendor app stores raw data and only applies its superior post-processing on display/export ? > Can you replace raw data inside a file > taken by the vendor software ?

That approach would, if feasible, indeed answer the question suspected above (namely where or when processing is applied) but I don't see how that might help in deriving the actual post-processing being done ?
