All it takes are different QC standards for the same projectors coming off the same productions lines to be different.
There was an old fable/joke/truth decades ago about Sony CCD chips for cameras. Even though they all came off the same line the best went to Sony Broadcast, the next best to Sony Industrial, then to Sony Consumer and the bottom of the line were sold to Panasonic.
Another possible example is Shure SM58, SM48, PG58.
There is a importer/assembler of Chinese mics (who, I can't recall) that QCs the capsules and sends back something like 98% and builds from the rest. The finished mics are 2-3 times more bucks but much more consistent.
A billion years ago GE who only sold Talaria light(oil?)valve video projectors decided to broaden their market below the $80,000.00+ projectors and started OEMing NEC 3 CRT projectors to get some install market share. While I was at Telaria school I saw some of the first ones to come in. Months later I'm installing the same model NEC projector and one input will not work. We were on the phone to NEC for 2 days and they had no clue what might be the problem. A synapse fires and I call GE tech support. They instantly said the reason the second input won't work is because it's TTL only. NEC did not know this. GE did.
Later I saw the identical NEC and GE models side by side at the famed Infocomm shootout (back when it could be a career changing event, guessing which would be the first to blow, Barco or Ampro) and the GE kicked the NECs ass.
Yes identical can be very different. Don't know if it is in this case.
