[OM] Metering with bright screens

I am pretty sure that it is only the OM1(N) that has a problem with metering with a brighter screen. In Franz Pangerl's book "The World of OM Systems" he mentions that the 1-5 and 1-7, which are clearer than the 1-13, let more light reach the metering cell and therefore offer an intrinsic error unless the camera is recalibrated. Now, the OM2 in Auto would compensate anyway as the meter measures light reflected from the film. The later cameras don't have a metering cell in the pentaprism and so the change in light transmissions levels offered by a brighter screen does not affect the exposure.

I think...
