Also, for what its worth, there's always some compression when taking raw game captures and sending it through a few different things for upload. Plus, when you explode a 4kish image on a screen there will always be jagged edges and so on, so while it looks bad when you click on the thumbnail its never going to give you a perfect example. Here's some example captured at full resolution direct from my Xbox, looks cleaner of course but as soon as you expand it you can still see jagged edges and so on, despite the image looking clean while I'm playing on my TV.

So a lot can depend on perhaps where you sit, as well as what your TV is and its own capabilities. I sit about 8 foot from a 55inch TV and I can't resolve jagged edges and stuff from where I am. If you were sitting 2 foot away from it then maybe you could.
There's also a significant drop in quality I've noticed between capturing the shots, downloading them and then uploading them here. The raw image on my phone looks a lot better than whats been uploaded there. So take every single screenshot with a cup of salt as the image will be sharper, cleaner and less blurred prior to uploading, on the console and while playing.
