Williamson also accepted a longer series would be more 'revealing'
Virat Kohli said future editions of the World Test Championship final should be played as a three-match series after his India side were beaten by New Zealand in the inaugural showpiece match in Southampton Wednesday.
New Zealand triumphed by eight wickets in a final extended into a sixth day after two days were completely washed out.
The Blackcaps, claiming a first major world title, chased down a modest target of 139 after their impressive pace attack restricted India to 170 in their second innings.
India captain Kohli, twice dismissed in the final by Royal Challenge Bangalore team-mate and towering New Zealand paceman Kyle Jamieson, the player of the match following a seven-wicket haul, insisted his comments were made "not because we're not on the winning side, but with the aim of creating an "absolutely memorable" saga.
India, who will remain in England for a five-Test series against Joe Root's men starting in August, recently won 3-1 at home to England after coming from behind to complete a stunning series win away to Australia earlier this year.
New Zealand captain Kane Williamson, having experienced the pain of defeat in two successive 50-over World Cup finals, with a 2015 thrashing by co-hosts Australia followed by an agonizing Super Over loss to England at Lord's two years ago, unsurprisingly took a different view.
Williamson steered New Zealand home with an unbeaten 52 to follow his first-innings 49.
Williamson shared an unbroken partnership of 96 with fellow senior batsman Ross Taylor (47 not out).
Scheduling a final two years in the making was difficult enough for the International Cricket Council, given the vast number of bilateral matches arranged by leading cricket countries rather than the global governing body.
Williamson accepted a longer series would be more "revealing".
Nevertheless, Williamson said there was no doubting both finalists' commitment to this match.
