raspberry_256x256_rgb565.h doesn't match raspberry_256x256.png in pico-examples/pio/st7789_lcd

[d-c-d]

in the rp2040 pico-sdk at https://github.com/raspberrypi/pico-examples.git
in the directory pico-examples/pio/st7789_lcd
there are two related files
raspberry_256x256.png
and
raspberry_256x256_rgb565.h

how was the file raspberry_256x256_rgb565.h generated, since the suggestions I've tried from our friendly LLMs don't seem to generate bytes that match the 16-bit RGB value in the .png file

I was guessing that the presence of both the .png and the .h image files would indicate that they were meant to indicate that one was derived from the other.
