No, because like all patents, they can claim all they want, but
what is actually patented, is their claims minus all the prior
art, which they often don't bother to specify.
It's therefore very, very difficult to see what is novel in their
claims. Certainly none of the individual steps are novel, so
one can only conclude that the combination of steps is what
is claimed to be novel. Certainly swaping one target curve
("Gamma 2.2" or "Gamma 2.4 with linear segment aka sRGB) for
a curve which is "Gamma 3.0 with linear segment" is nothing
to make a song and dance about.
