2008 Paint Question

My bed was repainted by a body shop recently after I was rear ended a few months back. I found the below spray out card in the truck when I picked it up. I was wondering if maybe this was the exact mixture for the 8P4 code or if this was an adjusted mixture to match the existing paint. The bed is identical to the old, weathered, paint on the doors, etc. Could they have used a spectrophotometer to get a blend that matched the rest of the truck? Could the percentages shown possibly be the adjusted mixture?

 

Now the silver mica. Paint code 1E7 I think, there are 5 different shades of that one paint color

 

I just contacted the body shop and those numbers above are the adjusted mix to match the old paint! Guy says it’s a water based paint and needs to be painted in a controlled environment.

Can a PPG paint store mix this mix?
