And why are color papers not available in different grades
to balance with the neg contrast?

Color materials have a longer scale than black-&-white materials. Also
there is in fact a significant difference in Kodak's RA4 Endura, Supra
and Ultra papers. The Ultra is about 1 grade higher in contrast when
compared with Supra which is about 1/2 grade higher than Endura
Metallic.
