Exactly!
Yes, but the video posted by @Ocfos is 4 years older than the EA lighting change. And, if I’m not mistaken, that video was the first Boundless promo video, still showing builds and a world gen engine from Oort Online. If you want a clear picture of the more known Early-Access lighting, you need to see the second trailer: Second Trailer.
@Ocfos, also, there were at least a few changes to the game graphics. The first and major one was when the game went from being made in Java to being made in C++ ( Topic about that). A lot of things were lost because of that, including the clouds, which are not present in the second trailer. There were also changes to textures, planets and lighting itself, which is the change @Buugi is referring to.
