Where to get Webb's source data, filter by filter and how to generate your own images:

No JPEGs, no noise removal, or color scheme by NASA.

Seek to 19:35 and watch this guy cycle through the different color filters of the same nebula.  You will see one where the nebula's gas has disappear and only the stars are visible.  It's like Webb has X-ray vision mode.
