User interface + Monitor very dark & contrasted

Hello,

On my new MacOS (Catalina), I noticed that Premiere Pro interface (including monitors) is very dark & contrasted. You can see it below. At left, the original picture. At right, the picture in Premiere pro interface. You can notice the problem. There is no Lumetri / post prod effect on the picture.

Note : When I export the picture, it doesn't export it darker/more contrasted.

I tried to make the interface lighter in the menu, but I doesn't affect pictures in the monitor.

Thanks for help !
