Dynamic range is why to support more bits, but that's oblique to adding more intermediate values by using floating point instead of integer. For example, using 16 bits instead of 12 to address the perceivable spectrum range only is enough on its own to have more than a full order of magnitude greater than perceivable gradations. > GIMP’s GEGL pixel engine deals natively with such things.

Adobe's product here is probably After Effects, and it supports formats such as ProRes, where the originals are integer 10 or 12 bits/channel.
