Why does that only come from Webb images? You weren't getting that same sensation looking at the Hubble images before? If that's true, then welcome to the club! It took you a bit longer, but we're happy you're here now. ;P
You're making the assumption the poster meant they didn't have this feeling before. They might just be repeating that, once again, it's difficult to do this with Webb. Hubble is irrelevant. Anything else is irrelevant. They're talking about the pictures here in front of us.
