Thanks for the paper. I had seen one article saying the 20 to 40 Jupiter radii for the object might be due to moons. The circumplanetary disk seems to be the better answer and the paper states it to be 100x brighter than if it were a Jupiter size object. That seems to put the exoplanet at a 22.5 magnitude.
