If you convert the ascii characters at the start you find: "icon_ui_barrier_button_up_Bitmap". Could be a custom encoded file format. You have to look for usual things like tags or width and height maybe computed based on data size, see where pixel data starts etc. Best is to disassemble the firmware and see how it parses it
