After further verifying by Guru, if the brightness is turned *way* up, the background is visible even on PCB (see attached finalap2_pcb.jpg). So it's possible the default brightness is very low (both Guru and the linked videos seem to confirm this).

this and the overly bright image in final lap in general seem like a gamma problem. Arcade monitors did generally display darker, we see this with a lot of Capcom games, the 'grey boxes' issue in emulators, but it's a little surprising to see it here because as fas as I know the other Namco System 2 games seem to have relatively normal looking output levels.

how are the colours generated on the Final Lap boards? is there a resistor network that differs to the other Sys2 games that could result in darker overall colours, or is it maybe just a monitor adjustment thing given they were used in dedicated cabs.
