I really don't think parrots attention is to compete with DJI on a financial level or market share, what I do think is they wanted to offer a decent aerial camera platform at an reasonable cost for their customer base with some unique features. I don't see much in the way of camera features improving, you want features you gotta pay for them. I do think they have a serious safety concern in revamping the RTH to incorporate a user defined RTH Action & Altitude.
getting back to your point the only way at this time is the display in FF6, Parrot states that adjustments to EV, SS, Exp will be displayed in real time on the screen.
The Anafi is far from being a professional photography/video drone, but simply a mid-low end platform with a very decent camera and features. JMO
