The information on Wikipedia (en) is misleading and incorrect.
The numbers 2965 and 6355 refer to the number of kanji code points in the first level and the 1st+2nd levels of the JIS X 0208 standard. Some 1級 kanji are not encoded in any of the JIS standards, and in the past there was never a 1:1 correspondence with the JIS X 0208 kanji and the 漢検 準1級/1級 lists. Some of the JIS X 0208 kanji literally have no historically attested readings.
The numbers on Wikipedia (ja) sound about right. When you add the "head" character kanji and the 旧字体 variants, you get around 3000/6000 distinct glyphs for 準1級/1級.
