Depends on which type of aircraft you are talking about I guess. On the A340's in row 1 and 7, the screens are extended out on an arm from the seat. I have not noticed that these would be smaller then the others though, but perhaps someone who has recently flow on one of these birds in row 1 could enlighten us. But I know that the screens in C are bigger then the ones in Y and Y+, so I would be very surprised if the screens in row 1 and 7 would be smaller.
