I don't think so, at least not very much decrease. I think the fuel will
divide among the functioning injector nozzles. This is why the pressure
increases when one is blocked, the fuel is forced through a fewer number of
orifices, causing a greater pressure drop across them.

But there is noticable change in pressure, just in flow. The flow is
very high. I could see that if 1 nozzle was plugged that the other 3
would have increased flow but I can't see that the total amount of fuel
delivered would be double. Fuel flow is measured by a spinning wheel
and is not pressure related.
