Filmmakers pay (or rent) $200,000 for a camera and $75,000 for a lens to ensure the largest sensor and highest data capture bandwidth possible, so that there is sufficient data inside the image, even in the pitch black shadows, which later can be manipulated, downgraded, color corrected, etc. You start with 100% even when you need 20% of the quality you captured because you can always get less, but never more.

The software that converts low quality to high quality pretty much tries to guess what might have been in a certain area, and gives you a version of what it “could have looked like” (in the best case scenario), and just like slow motion software tries to interpolate missing frames between real frames, you end up with ugly artifacts, because it is a guess, not a real captured image. Now, that might look cool for a casual user or even impress some people.

The thing you see in the movies where they take low resolution footage out of a surveillance camera, magnify to a blurry license plate, then magically a high resolution number appears, is a fantasy. Such a thing would only be possible if you film in 4k or 8k wide angle and sharp focus, and then you can still see a small slice of the image at 1080 or 720 resolution; or even better, if you have a surveillance camera with DSLR photo resolution taking high res sequential pictures (not video) then you can magnify these high quality shots up to poster size and still see good detail in the details of the respective image (but also, only up to a point).
