I think you might be confusing 1994/5 with 1995/6.
The latter was the stop gap season (otherwise known as the Centenary Season) before Super League began. It ran from Aug 1995 to Jan 1996 and was interrupted for a month because of the World Cup. It was an 11-team comp, so just 20 games each at an aggregate of 606,728 according to the Rothmans.
1994-5 was the last 'proper' winter season, running from August to April and the aggregate was 1,330,538, a slight decrease on 1993-4.
