I'm using the same driver (417.35) on a fresh W10 install to test.
I initially had trouble importing the registry but just had to allow admin access to the key.
First impressions; There may be a difference, but is more of a 50% improvement than 100%.
I haven't used W10 for months but compared to my good W7 machine the colours are awful in W10 - over-saturated and the whites look harsh and blue-tinted compared to the 'creamy' W7 colour temperature.
