Not true. I get the same scaling options on my 4K monitor as I do on my Retina display.
I'm not running the latest os.
On my displays I could only get the list of resolutions for my monitor, even holding down alt with preferences.
Meanwhile apple displays showed this dialog:

Maybe the latest OS allows it?

Yeah, maybe it's the OS version. I'm running Catalina and I see the scaling options from that screenshot for my external non-Apple monitor.

I don't know what you're seeing but the retina scaling options don't appear on any non-Apple display I've ever used. (Unless I hack the kexts.)

You generally have to use the right equipment -- using mini displayport or thunderbolt 3 instead of HDMI, depending on the generation. It's definitely finicky (much like getting guaranteed 4k60 output, especially through a dock)

Ah, maybe that's the key, I almost exclusively use hdmi.
Works for me, I'm using two fairly new dell 4K screens, as far as I know it works on any hidpi display

It does for me on both LG and Dell monitors.

Also, apple has a tendency to support fancy features ONLY on its own hardware. I know apple retina displays allowed display scaling, but non-apple displays only let you set the absolute display resolution.
