Blue dot on Canon eos M3 LCD

A few days ago a blue dot/smudge appeared in my canon’s eos m3 Lcd screen. The blue only shows n lcd, not in the photos/videos when transfered to laptop.

Does anyone know what is this and how to fix it?

It may be a stuck pixel,

Fully charge battery. Turn the camera on; go to menu and select “manual sensor cleaning”. Restart camera and problem should be fixed.

Not solved. And it looks more like a smudge with blurred edges than an exact pixel.

dead pixel on a LCD is usually white... it seems that a blue dot is likely software related.
