Outside of leakage current CMOS/MOSFET circuitry draws current during state transitions. So, yes, more bits flipping per unit of time will cause additional heating, sometimes dramatically so. This is the reason the last generation of iPads get so hot: Four tomes the pixels means that you have the potential to have four times more bits flipping in the display processing pipeline, hence more heat. Try running footage where every pixel is changing on every frame and see what happens.
