That looks similar to the spot you get when you put pressure on an LCD screen. Since it is close to bezel, it could be an issue with that. Or it could be a defect in the screen. It could also be caused by EMF or a magnet.

Well weirdly it's gone now, I have no idea how, should I worry?
I could turn on the warranty

Hard to say ... if the warranty ends next week, then I would get a new one ... if you have another 6 months I would wait and see.
