I would be interested in how much enhancement occurs with the processing of the raw data. The "stars" have a very JJ Abrams look to them.

You mean the six-way flare? That's probably the least enhanced part, it's a consequence of the panels being hexagons, and the stars being point sources of light.
 
I've seen a few videos about the new images so far. Here's one that I thought was good enough to pass on:



This is Fraser Cain.

One factoid about Stephan's Quintet: The galaxy on the left is actually a lot closer than the other four, about 40 million ly away, whereas the others are between 210 million and 340 million ly distant. In other words, it's closer to us than it is to the other 4 galaxies. The image has such good resolution, I think you can even make out some individual stars within the galaxy.

And this one has a lot of information about upcoming science missions:



This is from Bloomberg and it's 39 minutes long, but good production quality.

https://en.wikipedia.org/wiki/Inflation_(cosmology)#Motivations

Inflation resolves several problems in Big Bang cosmology that were discovered in the 1970s.[26] Inflation was first proposed by Alan Guth in 1979 while investigating the problem of why no magnetic monopoles are seen today; he found that a positive-energy false vacuum would, according to general relativity, generate an exponential expansion of space. It was very quickly realised that such an expansion would resolve many other long-standing problems. These problems arise from the observation that to look like it does today, the Universe would have to have started from very finely tuned, or "special" initial conditions at the Big Bang. Inflation attempts to resolve these problems by providing a dynamical mechanism that drives the Universe to this special state, thus making a universe like ours much more likely in the context of the Big Bang theory.

The idea is that 99% of the universe's expansion happens in the first nanosecond of the universe. Inflation sets everything up in less than a blink of an eye.

I think its going to need a supercharger after these results. A universe that's 99.999% dark energy or something similar.

The reference is to inflation flattening out the inconsistencies early to allow for the later formation of galaxies in stead of an immediate universe of only black holes. Not at all your claim of what it meant.
“Later” being a relative term.

Inflation sets the seeds for all galaxies.

We know of this week there are many more than thought.

Thus the model will change. It does every day. Still doesn't match the data...
