Your settings for Destiny 2 indicates that you have set the FOV to 76.366893 (this is a multiplier, true vertical FOV is 45.42), while you have it set to 90 in Extraction which is almost twice as high.
With these settings a 2x scope in Extraction will have the same FOV as your hipfire in Destiny 2, which is not ideal. You should whenever possible match the actual FOV for hipfire, which makes the calculation more sensible: https://www.mouse-sensitivity.com/?share=2e2438bfa7d4a1a39a04f9ea08f455b7
