Those clips if you look from underneath have a gap where you can prise a screwdriver and flick the caps off. Then the visor just pulls out. Makes removal much easier.
I'm not sure you would have been able to get it out anyway! I tried to remove mine to put into my new one but it wouldn't budge!I was annoyed-left mine in the JCW F54 for the new owner-instead of transferring to our new SE-then felt better as I realised we'd had anthracite headlining and our SE is beige!
