This applies when RAM is used as temporary cache or something that can be instantly freed the moment it is needed otherwise. This doesn’t really work for justifying higher RAM use by KDE, unless you would never need that RAM for anything else anyway.
I use KDE because it is good, though. Also I don’t think KDE even uses more RAM than other DEs that are designed to be lightweight. Last time I compared, it used the same or less memory as LXDE.

Firefox without any website loaded uses more RAM than a full Plasma session.
Well, depends how you’re using it. In my case, for example, I don’t have a printer, so I could turn off the entire print manager system/service and save a bit of unnecessary RAM. And if you’re trying to be economical about RAM usage, things like fancy window decorations, window animations, and other purely aesthetic stuff like that can of course go. But, really, what features are necessary versus unnecessary will depend on you and what you’re using your computer for.
Or did you just mean what features does KDE have?
In that case, the answer is basically, all the features. Like, KDE is the quintessential ‘everything and the kitchen sink’ desktop. You name it, they have it … or it can quickly and easily be added. Any feature you can think of from any other OS or desktop, chances are KDE already has it or at least can do it with just a little tweaking.
For an example, I think my favorite feature would be the ability to set custom window rules for each application or even each sub-window within an application. Setting rules that dictate the size and placement of that app’s windows, their transparency, which virtual desktop they open in, whether they show up in the taskbar or not, whether other windows can cover them up or not, etc. I use those rules extensively in my workflow to make sure each app always goes exactly where I want it on my multiple monitors, stays there, and behaves just how I want it to. (For example, I want my system monitor to be 80% translucent in a certain corner of the screen. I want my timer app to always stay on top, and in a particular location on a particular screen, I want my time tracking spreadsheet open on all desktops, but always in the background so it never covers any other window, and not cluttering up the taskbar. I want the terminal to always open maximized on my left monitor, and for it to be 100% visible when active, but 80% translucent when not active. With window rules, I can make all of that happen.)

Yep. KDE is feature-rich, but it’s also highly optimized these days, and the RAM usage is actually competitive with the best of them.
You can get RAM usage lower on a very stripped down, barebones system, but if you want a full ‘normal computer’ desktop experience that has all the things you’d expect a computer to have, you’d be hard-pressed to find one that uses significantly less RAM than KDE. (Yes, there are some that get lower … but not a lot lower. And unless you’re running on some extremely limited hardware, are those extra 20MB of RAM really going to make a difference in your everyday life?)
Also, higher ram usage by programs makes it less likely that their actively used RAM (ie what it is actually currently using) fits in your CPUs caches, making them run slower.

And KDE can be even more efficient if you go into the settings and tweak things a bit, turning off some unnecessary features that are on by default.
Which features? Asking because I switched recently to Linux.

Which features are unnecessary I meant. 😁
The difference being that in the one of those cases you still need to open a browser instance before you are able to browse the web.
