Seems most people don't post pics of their 911s with front plates. As a result, it's hard to see what they look like until they're on your car.
I guess in NYC it's strictly enforced as it's common to see Porsches with front plates. Here's an example I snapped on the street. A beautiful 991 Targa.

 

I am fortunate to live in a place that only has rear plates. But every so often there is noise in the news about the Cops wanting them. For 'Public Safety' they say. No big deal on bigger cars/trucks, but they really do ruin the front end of smaller sports cars.

 

Here's mine with the front plate bracket on.

Note it is a slightly different OEM front plate bracket for cars equipped with active cruise control (such as mine).

With my winter wheel set on Carrera S wheels:



And with my Carrera Classics with summer tires:

 

I've been pulled over when I had a Corvette for no front plate. Not worth the hassle for me or the extra attention from VA State Troopers so I had the front plate bracket put on mine.

 

It would look slightly less better without the dealer bracket on it with the dealer name and phone number...
