The planets will still just be star-like bright dots, but we will get some useful new spectral data, and be able to image much smaller and more distant ones. https://webb.nasa.gov/content/science/origins.html

> Webb will also carry coronagraphs to enable direct imaging of exoplanets near bright stars. The image of an exoplanet would just be a spot, not a grand panorama, but by studying that spot, we can learn a great deal about it. That includes its color, differences between winter and summer, vegetation, rotation, weather...How is this done? The answer again is spectroscopy.
