If you chain multiple panels, you need to give --led-chain=2 in this case. You find these details in the README: https://github.com/hzeller/rpi-rgb-led-matrix#panel-connection

Otherwise, the output of the first panel is just interpreted in a weird way, that looks like 'high contrast' as you describe.
