In that case he didn't read his own link.
The discussion I linked to specifically has to do with atmospheres in-game looking thinner than they did in marketing materials. Stars are only one part of that (see below). Photos like the one in the post I linked are what got many folks excited about Odyssey in the first place. There is a reason the marketing team went with a photo like that.
If I wanted to I could paint a few white dots into the reddit screenshot, the atmospheric effect would be unchanged. It's purely an artistic reason to display the stars.
I disagree. The screenshots you posted clearly show deep space "bleeding through" the atmosphere much more than in the marketing material. Yes, stars are one aspect of that. But the color is as well. Notice how the blue sky you linked to has a darker hue.
The two skies look very different to me. Clearly I'm not the only one that thinks this.
This isn't the only case of Odyssey marketing material not matching up with reality. I agree it's not the worst offender
by far. But given this thread is about atmospheric lighting I think it was an interesting contribution, that's all.
