That's correct, the Steam Link is a thin client for your gaming PC. From a consumer perspective, people have been rocking 4K TVs and 4K PCs for a few years, and even consoles have been outputting 4K (even if they're rendering less) for a while, so one would hope to have seen some sort of 4K offering. I can see discussions on the Steam forums as far back as 2016 of people streaming 4K in-home from PC to HTPC or similar, so it's certainly _possible_, even 4-5 years ago. I've done some 4K streaming from my gaming PC to laptop hooked up to TV in living room in the past without any (more) issues than I usually have being a purely Linux gamer. According to a topic near the top of the Raspberry Pi / Steam Link, Steam Forum, 4K is _possible_ (no indication of what it looks/feels like) with a Pi 4B these days.
