So I just watched "Darmok" and I have to say so far I'm a little bit disappointed in regards to picture quality. While the scence on the planet looked absolutly outstanding, I found everything on the bridge a lot less sharp looking then in previous seasons. I thought it was especially note worthy everytime there is a close up of Jonathan Frakes. In earlier seasons one could literally count every little wrinkle in the actors faces but if you look at Frake's forehead in "Darmok" it seems almost a bit hazy.
Again it still looks very good but the previous seasons just seemed sharper. Maybe it will get better in the next episodes.
