The dimming of cabin lights for t/o / landing may be many a company's procedure but it is by no means a CAA/FAA mandatory procedure. It is recommended by the CAA/FAA but is not a ruling.
Any chance to get used to the darkness before all power fails is better than from complete brightness to pitch black, even if it is not the full 30 mins.
The reason why pax may use their reading lights is because as stated above this procedure is not a ruling and to some pax who may not understand why it is done, it is just seen as an inconvenience!
