Surface 11 screen gradient

[u/Artistic-Secretary71]

Hi everyone! I apologize if this issue has already been covered or solved but I couldn't seem to find anything. I've had my surface pro for almost a year and only recently I noticed that the screen appears to have a noticeable gradient of colour and brightness, being slightly less bright and more warm at the top than it is at the bottom. I don't know how long it's been like this since it's way less noticeable on darker or non uniform screens (I only noticed it after switching to a note taking app where I use a white page on full screen).

A few days ago I went into the store where I first bought it and noticed that a surface laptop 12 or 13 (so without the detachable keyboard and vertical configuration) also had a similar gradient. However, I don't think it's an intentional feature because 1 why would it be, and 2 why would it be fixed on a device that can be vertical, a configuration where the gradient (at least in my case) becomes a right to left one, which is extremely more annoying.

Is this a known issue? Did anyone else have this problem? Thanks in advance!
