Camera Effects

Even with all background effects disabled, it appears that Zoom automatically deploys an effect to reduce depth of field considerably - far more that the native camera actually displays. This is clear to me as if I simply turn my head (with no background effects enabled) my glasses and the side of my face go out of focus. In looking at the camera via its native app (or even in Teams), this is not what the camera itself is creating. Is there some way to disable this annoying effect in Zoom ?
