If I cancel January score, will law schools know and continue with the review of my applications?

I'm taking the January LSAT but already applied to all my schools, indicating on the apps that I'll be taking the future January LSAT (so presumably they're holding my application until the Jan. score comes in).

But in the hopefully avoidable event that my January LSAT score is lower than my present score and I decide to cancel it with score preview, will law schools automatically know that I cancelled my Jan. score and proceed with review or will they still hold my application, expecting Jan scores to come in? Am I supposed to update them that I cancelled my score or does LSAC send a report?
