Color Shift

I uploaded a jpeg to the app. I'll put it down below. If I reset and zero all the color grading controls, should the colors be the same as the original jpeg or will the app change them a bit? In the photo I uploaded, the reds are a little muted compared to the original even if I zero all controls. If I click on the before/after split view icon I'll see the difference. Just curious if this is by design or something due to browser interpretation. Thanks!
