What's Up with Star Trek on Netflix?

All the effects were redone awhile ago. Doesn't really have anything to do with Netflix, I think it was done for its release on DVD.

You're looking at the remastered Star Trek with the CGI planets, ships and special effects I'm sure. They did that on the Blu-Ray as well.

So I have started watching original Star Trek on Netflix.
We have a 4k tv (at least I think that's what it is, I'm not the techy in my bunch).
And I am just mesmerized by how GOOD the show looks, especially the space sequences.
The planets are glowing!

It's been a long time since I watched original Star Trek, but I don't remember it looking so vibrant.
Did the planets always glow?
Or did someone beef up the effects before they put it on Netflix?
I assume they cleaned it up, remastered it, etc.
But it's just so sharp and impressive looking!
