I made a second comment where I addressed that. The JWST is designed to look for galaxies over 13 billion years old. GN-z11 is only estimated to be 4000 light years. It's actually a pretty similar size to distance scale as Titan is from the Earth. The amount of infrared light from the subject is also relevant.

It's also important to remember that the solar system is very large compared to the planets and moons. Titan is only 5150km across, but 1.2 billion km away. To scale, it's not actually much larger than the farthest known galaxies. Luminosity is whole other thing, which I have no knowledge about.

It's moving relatively fast compared to what it's designed to view. As far as I understand the main way these super powered telescopes work is by focusing on a singular point over time to get as much data as possible. The closer something is, the less space it has to travel to move a degree across your vision.
