Yes, true, let me unpack that then:

- purity as in the sample is uniformly constructed of the right atoms but they are not in the right configuration

vs

- purity as in the sample contains atoms that shouldn't be there in the first place

and finally

- purity as in: the sample that purportedly did show room temperature superconductivity turns out to be the impure one and that impurity is so poorly understood that we currently can not replicate it accurately, but a test by an independent lab of the sample would verify the properties as advertised.

All of these are possibles, and not mutually exclusive.

The conclusions in the linked pdf suggest this may be the issue with LK99.
