There is only a very limited amount of enhancement possible with computers. It boils down to two things:
1) Zooming in. Many advanced video players can do this via a cumbersome interface, but it is extraordinarily easy with a web browser like Chrome where you just CTRL + Mouse Wheel or pinch zoom on appropriate devices.
2) Modifying image contrast. In this case I don't think you would gain anything from doing this. The contrast already appears sufficient.
That is really all there is when factual accuracy is important. When artistic value is all that is required, there are plenty of AI-based image enhancement
tools out there on the internet. Some of them can produce fairly incredible results, but they are just that. Not credible.
