Does anyone has seen such like this? If so, how can I fix it without a monitor replacement?

It seems like growing from inside

That looks like a failed display.

you can try plugging in an external monitor as a work-a-round

I've never seen a display look like that, but I believe it may be caused by liquid damage. I've seen those diagonal lines appear after liquid has gotten inside the glass usually from cleaning the screen (usually only on the corners and only visible at certain viewing angles -- usually it is hard to see and not that pronounced or covering the whole display). If not liquid, then it may be from moisture condensing inside the glass from being exposed to a very humid environment or from a drastic temperature change. This is the only thing I can think of which could explain all those visible issues.

A 2013 model is now considered "Obsolete" by Apple so official repairs are no longer possible.
