Are Retro Consoles like Retron Duo, 3. 4. 5. 6 considered to be emulation?

I've seen some runs on the forum being posted on these things like real Sega Genesis and SNES these days.

It is difficult to tell. It seems like most people just accept the fact that emulators and original consoles are sorted together and compared. Some games have them separated but they are very few. In my opinion it is emulation for sure but I know people who are uneducated about the subject post them as original hardware runs. I personally do not think emulator runs belong anywhere but I seem to be in the minority on that topic.
