You may very well be right that he's improved his acceleration. But without numerical proof of a breakdown of a route or even a chance to see him truly in action, it's hard to prove at this time. He was clocked at 22.8 mph, but the context of what route was being run, the distance covered, etc. was not revealed. It could have been a 70-yard catch and run for all we know. If we take Core's 40 time into account (4.47 seconds at combine, 4.37 at pro day), you're looking at between 7.64 and 7.8 seconds. If we took 70 yards divided by 7.64 seconds, you're talking about 9.16 yards per sec. In mph, that's 0.0397727 miles divided by 0.002122222 hours = 18.74 mph.
It's worth noting John Ross's fastest 40 time ever was 4.22 secs, which equates to 7.385 secs for 70 yards. That's 0.0397727 miles divided by 0.0020513889 hours = 19.39 mph.

So what I'm trying to get at is if we're taking the whole distance into account, it won't be 22.8 mph. It's a max speed of 22.8 mph at a particular point in time, and that speed is likely not going to be reached within the first 20 yards. Just watch this video of John Ross's 20-yard acceleration being measured. https://www.youtube.com/watch?v=rkoMJHBuzOM
His max speed during this 20-yard sprint is 16.68 mph. I think we would all agree Ross is faster than Core, so the fact Ross can't get within 5 mph of 22.8 mph in a 20-yard sprint means I doubt Core was able to accomplish that feat within a few seconds. So what I'm saying is that if Core is hitting 22.8 mph, it's after a much longer distance than 20 yards.

We can't get a true sense of his burst off the line simply by measuring his top speed of 22.8 mph, as that clocked speed likely came toward the end of a big run
So my point still stands that having such a great max speed doesn't necessarily translate to having great initial acceleration and explosion off the line, it could come from building up that speed over a longer distance.
We need a 20-yard sprint acceleration test with Core like the above video of Ross to get a true comparison of how good his acceleration is. You can't go based off of his top speed.
