In some senses, it's the other way around: Type 1 is stored more like OpenType in PDF.

PDF uses CFF (Compact Font Format) with Type 2 charstrings as a lossless compression for Type 1 fonts. When OpenType was created, Adobe adopted the then-new CFF approach for handling Type 1 outlines (entire fonts really) within OpenType. The other OpenType tables are in addition to the CFF portion of the font.

So in PDF, when Acrobat reports fonts as being "Type 1," they are actually CFF - just like that portion of OpenType CFF fonts.

More recently, PDF has added the capability to store additional OpenType layout tables as well. However, this facility has been little-used to date, AFAIK.

Cheers,
