If you have purchased this phone for work and camera was your main tool then lack of certain features may and will affect your ability to fulfil your business objective that would be otherwise possible.
Think of it this way: ex. you bought accountancy software and only after purchase you learn that there is no way you can create any reports - even if advertising material and specs sheets stated otherwise; and even though you can still use it for other things but one of the desired features (you have been sold on) has been omitted. This can be damaging, although depends on individual circumstances, obviously, if you don't use it for work that is..
Besides false advertising (read: lying, because that's what it is) is surely liable to regulators, and they should impose appropriate fine.
