Slight Discrepancy in RGB Values Extracted Using PIL/CV2

I’m trying to extract the RGB values from an image using Python’s Pillow library on my MacBook Pro. However, the RGB values I get differ slightly from those identified using online RGB color extractors (e.g. https://www.site24x7.com/tools/color-code-picker.html). I've also tried with cv2, which gives me the same value as PIL.

For example, with the below method I get: 249, 222, 253

However, online RGB identifiers give: 255, 221, 255

Another method I tried is googling "rgb color picker" and picking a specific combination of RGB values. Then, when I screenshot the resulting colour, cv2 and PIL again give slightly different values than what I input.

See code below that I used for PIL.

from PIL import Image

image_path = "Documents/screenshots/pic.png"

try:
    with Image.open(image_path) as img:
        img = img.convert('RGB')  # Ensure RGB mode
        pixels = list(img.getdata())
        print("First 10 pixel RGB values:", pixels[:10])
except Exception as e:
    print(f"An error occurred: {e}")
