Indeed, but as AHelper said, textInverse,(iy+TextFlags) will only get you inverted large-font and small-font text, and only until the next time the OS resets the flag (which is often). There's no way to make non-text pixels get inverted for drawing. What Tari has design you there is an intermediate piece of hardware that inverts the data going to the LCD. Tari, I need to map out which pins of the ribbon cable are Gnd/5+, D/I, W/R, CS, D0:7, and Gnd one of these days.
