Is Punjabi culture the most mainstream representation of Desi culture in the west?

From I've seen most of what the average uninformed typical uneducated shallow westerners thinks of as traditional Indian Desi culture is more North Indian Punjabi culture. This is because many of the first Indian Desi migrants to the West were from Punjab and many of them introduced their cooking to the West. Since most of the early Indian migrants to America and the U.K. were Punjabi they introduced their cuisine modified for western tastes to Westerners. That why most whites I've seen when they think of Indian food they say chicken tikka marsala which is just a very westernized Punjabi dish. It also due to Punjabis have a huge presence in India itself. I was in a class and my teacher told me Punjabis make up many of the actors in Bollywood films and songs like Tunak Tunak Tun originate from Punjab which have only helped to strengthen Punjabi cultural influence. Also Pakistan is majority Muslim Punjabi and they far outnumbered other ethnic groups in Pakistan so if one encounters Pakistanis aboard more likely than not they are Punjabi Muslims and most will learn about Pakistani culture and will only see Punjabi Pakistani culture. Currently in the Canada most Desis there are Punjabi and on Youtube one of the most successful Desi content creators is Dhar Mann who is Punjabi and most Indian culture he features in his videos in Punjabi with Punjabi actors, sikhism etc. So are my observation correct with how massive Punjabi cultural influence has been.
