Not quite, as jpeg usually uses a /lossy/ compression, which can induce 
visible artifacts (especially at high contrast edges, see the effect jpeg 
compression has on text or line drawings).

And 12 bits is enough for most sensors afaik, and packs nicely (2 pixels in 
3 bytes, easy to encode/decode); so 16 bits is a bit of overkill, and would 
slow down writing to the memory card. 

But yes, a really standard and open RAW format would be nice.
