gfx.drawPalettedBitmapFromFile

Question

I'm trying to figure out how to use  gfx.drawPalettedBitmapFromFile for displaying gray scale images. Will it fork for that?

Does the example here https://github.com/ThingPulse/minigrafx/blob/master/examples/ILI9341/DrawPaletteImage_4Bit/DrawPaletteImage_4Bit.ino help? Whether you get "true" gray scale also depends on the palette (i.e. the number of actual colors).
