Back in those days only tests that counted! WC win was great but that did not define IK! Test were the true pinnacle however 92 WIN started the shift toward LOI cricket due to how successful it was.
Imran Khan winning it had something to do with that - He was the biggest start in the game at the time and him winning it started the revolution of LOI cricket.
His victory did nothing for LOI game. You are forgetting the fact that the 1992 World Cup was established as the first modern World Cup anyway. It was the first World Cup played with colored clothing and under lights.
Regardless of who would have won the World Cup, it would have been a success.
The real revolution of ODI cricket actually started when Kapil produced the greatest cornered tigers moment in history and lifted the World Cup against arguably the greatest side of all time.
India’s 1983 World Cup win changed the complexion to the format. It created a craze for the format in India and brought the 1987 World Cup to the subcontinent.
This is a good read on how India’s 1983 World Cup influenced the format.
The 1987 World Cup was a trendsetter, an event that began the process that restructured world cricket and altered power equations within the ICC.
Until then, England and Australia reigned supreme, armed with a veto that allowed them to push aside all opposition to any ideas of theirs.
When the 1987 World Cup moved out of England, it marked the end of this domination and opened a window for other ICC members to assert themselves and start questioning unequal power-sharing arrangements in world cricket.
Moving the World Cup away was not simple. It required a complicated negotiation between two nations - their leaders, politicians, cricket administrators and businessmen.
The operation began just after India won the World Cup in 1983. The plan to get the World Cup to the subcontinent came from three individuals - Indian politician and cricket administrator NKP Salve (from Nagpur), Calcutta businessman Jagmohan Dalmiya, and bureaucrat IS Bindra from Punjab.

Without India winning the 1983 World Cup and the popularity of the format shooting through the roof in India, Pakistan and India would not have hosted the 1987 World Cup or even the 1996 World Cup.
It changed the power dynamics in cricket and as the article further mentions, broke the dominance of the western bloc (England, Australia) and saw the rise of India - and by extension Pakistan - as a major voice in cricket administration and not just mere pushovers.
The 1992 World Cup win had no such impact on the format and it came at a time when the ODI format was already very popular and the ICC decided to promote that World Cup further with colored clothing and lights.
That World Cup win brought a lot of relief to Pakistani fans who were bitterly disappointed to see their team slip up against Australia in the 1987 semifinal in Lahore, so the craze for the ODI game in Pakistan was already there.
The only thing that would have been different with Imran not winning the 92 World Cup is that he wouldn’t be the PM today and Pakistan cricket team might be more professional instead of hoping for magic, miracles and repeat of 92.
