OPV shouldn't affect steam at all. Steam comes from boiler pressure, not pump pressure.
You're right about pressure increasing with a finer grind. The reason you only got to 7bar was because that's all the resistance the puck could create. Greater puck integrity would push it to 9bar and then the OPV will kick in.

Also, how will the OPV setting affect steam?
Generally it doesn’t, but if you have the OPV pressure set low, you can find the machine occasionally ‘burps’ the excess steam pressure into the water tank.
