Most probably not. Usually, such titles are made up for entertainment purposes rather than being based on real events. There might be elements inspired by real life, but it's not a direct account of a true story.
I'm not sure. It depends on the specific context and source of 'New Look'. Sometimes things presented as stories might have elements of truth mixed with fiction.
One impact could be increased awareness. If it's a new look in a museum exhibit based on a true story, more people might become aware of that historical event. For example, a new display about a war using real artifacts and new visual interpretations can attract more visitors.
It can make the story more engaging. When the new look is based on a true story, it often brings a sense of authenticity. For example, if it's a new look in a museum exhibit about a historical event, it can draw people in and make them feel closer to the real events.
