With the above, that looks like classic 'overexposure' - you've got the photographers nightmare, a dimly lit scene with a single bright source of light. Unfortunately, yes, if there's no valid detail in that you're screwed in the fundamental term.
There's ways of dealing with it, but they're slow, labourious and they're more akin to film colourisation than video technique, unless somebody more experienced in this comes along with a better answer you might have to 'paint' the information back in, and that's slow and requires a lot of talent. Much like photographic film, once it's "blown" there's no information there to recover.
