I don't exactly know if this is a problem with everyone buuuut.. after the orbital update on intel HD 4000 the gamma seems waaaay to low it's barely possible to see on metal planets or lava, only on the lit up side, and earth-likes seem so odd with the added darkness, I don't believe this is the screen of the computer as I still have an older version that I can launch and see the differences, even the menu is very dark.
This is bug FS#2001 Check comments on bugtracker, I'm describe how you can temporary fix it yourself using driver color profiles settings.
