Not necessarily.

There's a big difference between building a tall building with a large uniform floorplate that takes up much of a block and a tall building that is thin, only taking up a tiny slice of a block, and thus allowing sunlight to pass through.

For this reason gloomy Vancouver for a long time mandated point towers, for the purpose of maximizing light.

Paris' status quo of uniform 6 story streetwalls could arguably let in less light than a mixed amount of much taller thinner towers on 3 story podiums.

Most of New York has 10-15 floors buildings with wide streets. Light and fresh air isn't a problem. But you can't really widen Paris street and the uniformity of the architecture is what makes it a beautiful city. Tourists aren't flocking to Paris to take pictures of some boring glass and concrete buildings.
