While OpenEXR will give you an improvement, it would still be a 
comparatively poor choice, as its absolute precision varies considerably 
between dark and bright regions of an image, so you'd have different 
quality on high plateaus than in low plains.

For your purposes, any classic file format with a 16-bit color depth 
would be better suited, such as 16-bit png.
