i want to see the camera sensor on that thing
There's some more older stuff on their website [2]; the test images from 2020 were a whopping 31694x31646. They have interactive zoomable images for those here [3].

One visual difference would be that they dont have the rgb grid filters of consumer devices, which is why all astronomical images start off as black and white.
They have to meet very challenging specifications, such as high quantum efficiency (what percentage of photons get detected) across a broad spectral range, fast readout with low noise, and minimal persistence across exposures (meaning that if you image a bright star, you don't see a faint trace of it in the next exposure).
As I understand it, there was no single company that could even manufacture the required number of CCDs on time, so two different manufacturers had to be chosen.
