Whenever a full range video is input, since the YUVJ* formats are not
listed as supported for this filter, a range reduction takes place
through the auto-inserted format filter, forcing the conversion to
operate on a limited range,

However the filter handles full range videos perfectly fine, so adding
support to YUVJ* formats will allow skipping a conversion step, while
providing completely identical results.
