IMX264 sensor not accepting colors correctly.

I'm using NVIDIA Jetson Nano with L4T 32.7.4 and IMX264 camera sensor. I have configured the .dtsi file and I can successfully obtain an image using nvarguscamerasrc using GStreamer, and also argus_camera using the jetson_multimedia_api. However, I visually see that the camera does not recognize the colors correctly.

I've tried to write a Python script using OpenCV, and here is the code:

import cv2

cap = cv2.VideoCapture("/dev/video0", cv2.CAP_V4L)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 2432)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 2048)
cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter_fourcc('R', 'G', 'G', 'B'))
cap.set(cv2.CAP_PROP_CONVERT_RGB, 0)

if not cap.isOpened():
    print("Error: Failed to open camera.")
    exit(1)

image_id = 0
while True:
    ret, frame = cap.read()
    print(frame.shape)
    print(frame.dtype)
    frame = frame.reshape((2048, 2432))
    if not ret:
        print("Error: Failed to grab frame.")
        continue
    frame = cv2.cvtColor(frame, cv2.COLOR_BAYER_RG2RGB)

    frame_resized = cv2.resize(frame, (608, 512))
    cv2.imshow("Frame", frame_resized)

    key = cv2.waitKey(1) & 0xFF
    if key == ord('q'):
        break
    elif key == ord('c'):
        cv2.imwrite(f"capture{image_id}.png", frame)
        print(f"Image captured as: capture{image_id}.png")
        image_id += 1

cap.release()
cv2.destroyAllWindows()

Here is the image I put up on my phone's screen: https://m.media-amazon.com/images/I/71Icb3wd6DL.jpg Here is the image captured: https://imgur.com/loQ30Bh

The script gives me a rather darker image, the nvarguscamerasrc pipelines give me a brighter view. Maybe I'm missing something on the OpenCV script.
