A2442 intermittent screen issue, black strip, macbook 2021 14"

I opened my Macbook this morning to find this ominous black strip down the centre of my screen. Devasted as I used my laptop the evening before and had no issues whatsoever.

I carried the laptop in my laptop case, in my bag to work this morning and then faced with this! I am quite protective over my laptop and cannot see how this could have happened due to any drops/bumps/damage.

I took it to a Mac Repair shop (not Apple) and they said they hadn't seen anything like this before, as this model doesn't have flexgate - which has seen some similar issues to this.

If you slightly flex the right corner of the laptop screen slightly and apply pressure to the bottom of the black strip, in the centre, Vertical lines appear and do display the screen as it should be. I've run my finger along and every single line of pixels does appear, at some point, but without the pressure, it just goes back to black or some odd, coloured lines throughout the area.

I feel like this shows the LCD isn't actually dead or damaged, but maybe seem like a connectivity thing? I can't seem to find any videos of someone actually deconstructing the screen to show what parts are inside, but maybe someone knows whether this still calls for a full LCD replacement?

Does anyone know of this issue with the LCD screen connectors, as screen replacements aren't offered outside of Apple unless I want to lose two-tone functionality.

But £700+ seems too steep when it doesn't seem like this is due to damage.

Cheers!
