Firstly, I think a lot of us who watch regularly are already picking up other clues already. You see a Merc with a predominantly yellow helmet - Hamilton.
Ferrari's numbers are now very visible. Driver names less so.
I suspect there are two concerns here - marshalls want to see numbers, spectators want to know who is in the car.
McLaren make the names easier. You can easily read the ALO on the side of Alonso's car.
Merc have number and abbreviated name on the fin. You can see the 44 on Ham's car. the HAM is less easily visible.
Haas have a very clear GRO visible on the fin of Grosjean's car, but I don't see the number from the side. Saubers have names on the fin and numbers on the side pod.
Most cars seem to have more easily readable numbers on the front. Merc have very good contrast and different colours - red for Hamilton, blue for Bottas.
I'm not sure that the side branding is that much if a help for the TV viewer. I just watched Hulkenberg go down a straight, the car is in shot the whole length of the straight, but you don't get to see much of the markings of the fin.
