Personally I think of an Improved cartridge as just that an Improved version of the original but like you thats just my thoughts. A wildcat is something that was created and made by changing the cases original projectile caliber or a complete re design based off another case that someone came up with in a basement or shop.
Quoting from Wiki/Google “ A wildcat cartridge, often shortened to wildcat, is a custom cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created in order to optimize a certain performance characteristic of an existing commercial cartridge, or may merely be intended as novelty items”
If we use this definition as true then some of the Improved cartridges are considered a wildcat but some aren’t. As i believe you can buy factory produced ammo for things like a 280 Ai from Nosler. That also means things that once may have been endorsed by a manufacture but has since become a “lead balloon” and fallen off the face of the earth could then be moved into the wildcat category if your have to order your own reamer to get a barrel cut because you cannot buy one pre built.
Very good question.

What’s the book title ?

The correct terminology has not changed in all the years cartridges have existed ...
Factory ammo can not be chambered and fired in a wildcat chambering. What makes it a wildcat is that fact.
Factory ammo can be fired in any improved versions whether they be Ackley Improved with 40 degree shoulders, RCBS improved with 30 degree shoulders or any other "improved" versions.
So "improved" versions are not wildcats ... If you can fire a factory round in it, it is not a wildcat.
There are several instances where a cartridge started out as a wildcat but once a factory manufactures ammo for them, they lose that status.
7mm 08 is one example.
Does it matter?
What’s in the name??
I tend to think of wildcats as anything that is not standardized- like the SAAMI post above. And that you cannot buy ammunition for either.
So most Improved cartridges I would lump under the wildcat name. Even if you can fire the factory version of the cartridge in your Improved chamber, it's not the correct ammunition for the rifle.
If the dividing line between a wildcat and a commercial cartridge is if any company makes ammo for it then wouldn’t my 219 Zipper be a wildcat again as ammo hasn’t been commercially made for it in 60-70 years? Ever since the 30+ year old wildcat the, .22 varminter, was adopted as the 22-250 the Zipper was doomed.
By the way Browning started producing wildcat 22-250 rifles in 1963 when no commercial ammo was available. Remington adopted the cartridge and put their name on it in 1965 along with producing ammo and chambering it in their 700 rifle.
Dad ordered his Savage 110CL (left hand) in 1969 from Elwood Epps with a straight taper Anschutz barrel and it is destined for my grandson as he is the only one to also use the “wrong” hand like dad.
But firing the factory round to fire form it to the improved version is what makes it an improved cartridge... it is not a wildcat. The factory round is the correct round.
(post 17) Shooting a 30 06 out of a 338 06 simply means you have chambered and fired an incorrect round... the 338 06 is not longer considered a wildcat as factory ammo has been made for it.
