This point on yes/no applying thermal noise removal is a major sore. One of the main effects of this operation on GRD data is to set the noisy boundaries to 1000 (from values that are typically < 10), which is not particularly useful. See this thread.
It would be nice if <thermalNoiseCorrectionPerformed>false</thermalNoiseCorrectionPerformed> would be consistent with the actual state of the processing (true?).
