This doesn't look like the classic stuck IR-cut filter where the whole daytime image, and especially greens such as grass, has a purple tinge when the filter is stuck open, allowing general IR in to the image.Beat it pretty good with the handle of a screw driver... knocked the focus all out of whack but did not fix the IR issue.

The night B&W shots show that the IR LEDs are on and the IR-cut filter is open, looks normal.
A bit of a long shot - I'm wondering if the IR illumination itself is stuck on when the camera is in day mode. And the hoodie, and hair, is somehow sensitive to the IR...

That could be checked, in daylight, by looking directly at the camera to see if the tell-tale red glow of IR LEDs shows, or better by pointing a smartphone camera at the CCTV camera where the IR LEDs would be visible if they were on.
Is the fact that the image pixel size and subsequent aspect ratios differ and also the field of view differ between the 2 images of no consequence?
Maybe that's just a result of how you made the captures and posted them?
IOW, objects appear to be in different locations or viewpoint between the 2...or it's my imagination (hey, I'm the first to admit my brain and eyeballs have high mileage).
Yeah, doesn't look like the typical stuck IR filter though I can see some magenta cast elsewhere in the image (e.g,, floor above). I can understand how different materials might look different but what I can't figure out is that if you look closely there's purple reflection on the otherwise black chair. Not sure how that works.
