Didn’t the Steam Link stream video from a full on PC? I’m not sure the 4K encoding and streaming in near-realtime story is particularly good even today, let alone a year or two ago when a 4K Steam Link might have been a possible hardware iteration.

Though they could have done 4K UI / other apps like an Android TV device I suppose.

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.

With a username like "DeliriumTrigger", I strongly doubt he's talking in good faith.

It's a reference to a song Sohcahtoa82.
