It took a while even once Hubble was fixed for people to figure out the processing to extract the prettiest pictures from it.

To explain that concretely: Hubble was launched in 1990 and was fully functional once got its eyeglasses in 1993. But it wasn't until April 1995 that Jeff Hester was studying photo evaporation in the eagle nebula and motivated by studying the concentration of different molecular gasses, created a color image by mapping the narrow SII, Halpha, and OIII molecular lines filters to RGB (a false color image, called SHO or the 'Hubble pallet' by astrophotographers)-- creating the iconic "Pillars of Creation" image https://en.wikipedia.org/wiki/Pillars_of_Creation#/media/Fil... .

Hubble's large aperture and freedom from atmospheric distortion and light polution obviously contribute greatly to the image-- but much of the purely aesthetic beauty of the image, beyond the target, comes from the process and processing choices as illustrated by the many lovely images of the same object created by amateur astronomers whos processing follows in Dr. Hester's footsteps. E.g. https://www.astrobin.com/lglsd8/ https://www.astrobin.com/i1wffo Today, SHO images of many targets are produced by advanced amateurs with relatively inexpensive equipment, resulting in many breathtaking images of a sort that never existed before these techniques were popularized by the Hubble telescope. (random example: https://www.astrobin.com/fzp6u2 )

By the same token the JWT likely has locked inside it a tremendous potential for images which are both intellectually and aesthetically pleasing waiting to be unlocked through the skill and practice of people working with the data and their discovery of targets best matched to the instrument and those processing techniques.

Targets which are likely to be particularly aesthetically stimulating (as opposed to only intellectually stimulating) are also only a portion of what gets studied. A differential spectral measurement showing an oxygen atmosphere won't be much to look at-- but it will have a tremendous intellectual beauty.

Maybe in the future we'll see one of the billionaire space spacefarers partner up with some amateur astrophotographers to launch some modest equipment optimized for making aesthetic images (e.g. using optical designs that are free of diffraction spikes, like refractors or SCT reflectors). Who knows-- they might also make some interesting scientific discoveries because it's hard to study the aesthetic beauty of the universe without finding intellectual beauty of vice versa.

It might also be that processing techniques from JWT NIRcam images help terrestrial astrophotographers make better images. There are some reasonably large windows of NIR spectrum that we can image from earth-- e.g. J-band from 1170nm to 1330nm has good atmospheric transmission. And there is a lot in favor for terrestrial imaging in J-band: Light pollution is much less there, wavefront distortion from seeing is reduced, scattering (which follows the inverse 4th power of wavelength) is vastly lower. As a result you can even image the stars in the daytime with J-band. The big barrier is sensors because silicon sensors are blind past about 1100nm. The sensors used by JWT's NIRcam cost about $350k each and have to run at cryogenic temperatures. But sensor technology is improving (e.g. https://www.qhyccd.com/qhy990_qhy991/ QHY990 is more like $24k), and JWT might help drive along development by finding targets and processing techniques that could also be applied on earth just as happened with hubble SHO.
