It doesn't seem to be that accurate, as expectation was for it to have smoother photo sphere, but it has irregular bulges (5 of them). I think they discussed it briefly in the press conference as well. It would be interesting to see if this would change understanding of general relativity and may be give a hint for a theory of quantum gravity.

I'm not sure how much we can truly draw from small irregularities in the image. This isn't actually a low resolution image. It is an algorithmically interpolated image created by comparing possible interpretations of the spotty and noisy data gathered from multiple points at different times processed against images of what we think a black hole should look like.

Look at the expectation examples in the scientific paper from 2013 that is, from ca. 6 years ago:

It matches quite good, I'd say. Page 4.

What bothered me more about the video is that of you watch the whole thing, he ends up talking about some theory which leads to another type of image prediction. He never actually explains why he chose to go with the former prediction rather than the latter.

The whole video was him explaining why the image would look the way it ended up looking. darkpuma was overly patient when explaining this to you.

You were a user acting in bad faith that very literally jumped in at the end just to write a troll bait comment in that thread. Your comment had nothing substantive to even do with any discussion, or even any relation to anything I said.
There is nothing complex about my original statement there. The EHT website itself has a gallery of simulated images and I'd like to know why he chose that one specifically.
In the video he says "just trust me."
This is a perfectly reasonable criticism, I don't care how many downvotes or personal attacks I get.
It has nothing to do with anyone "being patient." That thread was 90% bullying, which you are taking part of.
