The days are too dark

Hello everyone, with the real weather when it is cloudy and even more so when it rains it looks very dark when in reality here in the Canary Islands it does not look like this, maybe in Finland or Iceland if it will look dark but not Canary Islands and it’s no problem to give my PC- i7,2600 CPU 3400 GHz RAM 16GB, nor the Nvidia GTX1660 graphics card or my monitor that I have a Samsung TV 55 ´ of 4k and in the Prepard 3d V5.1 looks fantastic, some solution
