Of my copies my 7 element super-multi-coated takumar is little sharper than the 8-elemet I have when tested head-to-head ... but yes, for real pictures I cannot tell the difference.

That's probably the best way to tell from pictures - regardless of other mechanics the IR mark will always be on the correct place depending on the optical formula

Search around for the old discussion about the 8 element variant. I don't remember the details anymore, but the "typical" 8 element version lens body had a certain set of differences compared to the regular 7 element lens body. However, some people had copies that are 8 element - but the lens body was more like the 7 element version. I guess these are refered as "hybrid".

The rear element on this one looks like the the 8 element version, but the glass itself looks yellowed and as far as I remember the 8 element versions were not radioactive so I can't tell for sure.
