Can Pakistani Punjabis Read or Recognize Indian GURMUKHI PUNJABI??? Social Experiment in Islamabad

I bought a devnagri Indian Hindi Book in Pakistan a few months ago but I could not find or buy a Gurmukhi Punjabi book in Pakistan so I got an Indian Punjabi (Gurmukhi Punjabi) book off of internet. I turned it into a hardcopy book and took Hindi and Punjabi books with me to a park in Islamabad.
I asked Pakistani Punjabis if they could recognize or read Gurmukhi Punjabi
