The [OpenJPH example](https://pub.smpte.org/doc/st428-24/20241101-pub/index.html#sec-sample-codestreams) is missing the `-colour_trans`, which enables the Reversible Color Transform (RCT), which further improves coding efficiency. Note that the RCT is automatically enabled when TIFF is in the input format.
