FaceTime HD image quality on a1407 apple cinema Thunderbolt Display

I have just acquired an a1407 apple cinema Thunderbolt Display combined with my 2018 15" 2,6 GHz  MacBook Pro.

I am using the displays FaceTime HD 720p camera for remote calls, but the colours (funny bright) are a bit strange from my camera. I have attached screenshots also from the HD camera on my macbook, with much more calm colours.

Is there anything wrong with the camera? can I reset the settings somewhere? or would I gain anything from replacing the camera part in the screen?

Or is it just the quality of that camera

I have tried the same with different MacBooks connected and its the same result.
