Blinding white backlight ruins bedroom sexytimes

One of my favorite things to do with the OG-1 is to get into bed an hour early and noodle around with the lights off.

With the OP-1F, for some reason the sample background backlight has been inverted to a blinding white rectangle. Every other synth page has a black background. The white burns my eyes out in the dark and I can no longer enjoy late night sexytimes with the OP.

Please TE, add a setting to un-invert the sample screen and stop it blinding me in the dark.
