Not really. It’s just a normal Zen 4 CPU with some server features like ECC memory support.

I'm pretty sure all the Zen CPUs have supported ECC memory, ever since the first generation of them.

A lot of the Zen based APUs don't support ECC. The next thing is if it supports registered or unregistered modules - everything up to threadripper is unregistered (though I think some of the pro parts are registered), Epycs are registered.

That makes a huge difference in how much RAM you can add, and how much you pay for it.

Not officially. Only Ryzen Pro have official (unregistered) ECC support and not many motherboards support it either. AFAIK Threadripper doesn't officially support it either but I could be wrong.

Many boards support ECC even when not mentioned. Most ASUS and ASRock boards do for example.

The newest Threadripper 7000 series not only support ECC, but require it to work. It only accepts DDR5 registered ECC RAM.

Consumer CPUs were lacking ECC reporting, so you never really knew if ECC was correcting errors or not.

No, even the earliest Ryzens support ECC reporting just fine, given the motherboard used supports it, which many boards do. Only the non-Pro APUs do not support ECC.
