If you mean the photo I figured that was a recreation based on the ability to predict attributes from DNA like facial structure, hair, and myopia. Myopia was listed as a known characteristic in the ‘invalid’ image. It didn’t give his name and his own brother had to work to find his identity. They go looking for the him amongst the vagrant unregistered population where it’s pointed out that they’re looking for someone smart so he’s probably not going to be there.

It could be assumed that all genetically engineered people are registered so ‘invalid’ would imply not-genetically engineered.

Modern identification based on DNA is far easier in real life as he would still share many genetic variants with his brother.
