When I log into Google, for instance, from a private window on my iOS device (e.g. an iPhone 6 which has never logged into this account before from either the app or Safari) it is able to both identify that this is not only an iPhone, different from, say an iPhone 7, but also display the name of the iPhone in the "recently logged in devices" list. How do they do this? I'm not curious as to the iOS version, e.g. iOS 12, because I'm aware that the user agent will spit out something as follows:
Mozilla/5.0(iPhone; CPU iPhone OS 12_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Mobile/15E148 Safari/604.1
This snippet should theoretically only give platform (iPhone), version (12.0 Mobile, OS 12_1), and Safari build number with WebKit (15E148 Safari/604.1), correct?
Is there something else at play here? The one obvious difference that I could think of would be screen resolution, but the 6, 6s, 7, and 8 all have the same size screen with identical ppi's and thus the same resolution, so that would only work to differentiate it with a newer device such as an X/Xs/Xr. What do they actually use behind the scenes?

I'm not an expert in this field, but your question can be answered simply.
Browser collect almost all the data it is able to. For different purposes, but mainly to offer you advertisements (appropriate to you and your device) and offer you relevant topics (you're interests of search etc.)
Private browsing doesn't mean that you don't send any information to the browser, it still gets all the information it needs, but it just eliminates all the cookies and unnecessary information as soon as you exit.
"Your browser also reports its name, so sites know whether you’re a Chrome devotee or a Firefox user, as well as information about the computer system it’s running on, including your desktop or mobile OS, the CPU and GPU models, the display resolution, and even the current battery level if you’re using a laptop, tablet, or phone."
(https://gizmodo.com/heres-all-the-data-collected-from-you-as-you-browse-the-1820779304)
As far as the browser is able to receive all this type of information, it can also receive whether it is written in your device that it is iPhone 7, 8, Xs or etc. So it doesn't really have to guess according to screen size or something like that.
I'm not sure whether you was looking for a more specific (something like algorithm-based, of how it operates) answer, but the main idea is that it simply gets this specific information from your device.
