For saving png you can try my newly written example.

edward-ardu/picamera2_example/blob/main/SavePng

#!/usr/bin/python3

import cv2
import time
from picamera2 import Picamera2, Preview

import os
os.environ.pop("QT_QPA_PLATFORM_PLUGIN_PATH")


picam2 = Picamera2()

preview_config = picam2.create_preview_configuration(main={"size": (800, 600)})
config = picam2.create_still_configuration(main={"size": (9152, 6944), "format": "RGB888"}, buffer_count=1)

picam2.configure(preview_config)
picam2.start_preview(Preview.QTGL)

picam2.start()
time.sleep(1)

I took the data out and saved it with opencv and it did save it. And saving directly with picamera2 did not work for me.
