Should video be first thing on product websites?

We have car research product website. We have product page for each car model that has car photos, videos, price, features, specifications, alternatives, reviews and news.

I read that product pages with videos has higher conversion rate. Is it really true? Anyone has Done some similar experiment?

Currently we show image carousel in the first fold and there's video icon just below image carousel by which user can view videos too. This video play icon has Ctr of 3 to 4 percent.

Is putting video upfront on product landing worth an experiment?

I am bit apprehensive about this as we have majority traffic on mobile website and people need to have headphones to view videos, so, would placing video really help us improve engagement and conversion?
