It also makes it look pretty coming out of the box.

I’m sure companies run tests and have internal data. I’m skeptical that there are external studies because you have no actual coating/plating specs, just descriptions.
The irony of this is that the actual steel wears with use. How in the world will mil or two of any coating have any impact on durability?

Here is the bottom line. If you pay 20% more for some unknown type of chrome plating, then you should get 20% more durability. That means 3600 miles instead of 3000 miles.
I don’t think that will happen and I can’t recall any thread professing that type of additional durability associated with the type of coating/plating.
It is a fairly low quality disposable consumer product.
I bought a little used Shimano chrome plated cassette pretty cheap that had a pretty good amount of rust by the spacers when I opened it up. The history of was unknown to me, but I was surprised by it.
If you don’t like what I say, that’s fine. Just buy what you want.

I sure hope these numbers are hypothetical. 3600 miles is pretty lame for the life of any cassette unless you consistently ride in a slurry of mud and never lube your chain.

I’m guessing this thread will now spin off into cassette life where some will get less than 2000 miles and others more than 10,000 miles. Four to six is probably a better estimate.
And then it will morph to cassette longevity vs lube.
In a week, if it still on page 1, any semblance to the OP’s coating difference will be in the distant past.

It was hypothetical, but probably not that far off for an inexpensive cassette. I honestly don’t know the differences in material properties of lower vs higher end offerings.

As far as wear is concerned, inexpensive cassettes don't wear out any faster than say a 105 or Ultegra cassette. However, Dura-Ace cassettes are known to have a short wear life because all the cogs are Ti for weight savings. So 2000-3000 miles is not unusual for a Dura-Ace cassette. Most other cassettes should last at least 10K miles. I have 12K miles on my current cassette.
