It looks like HALIC offers very impressive decode speeds within its compression range.
And not just decoding speed but also encoding speed with difference of an order of magnitude. Some new results further down in the comments in this thread. Had it not been verified I would have thought it was a scam.

Champion! I wish you hadn't commented so ignorantly. Please also try to look at the processing speeds! Or you can also try not to comment at all...

It looks like LEA 0.5 is the champion.
And HALIC is not even close to ten in this [2] lossless image compression benchmark.
