This is BS. Nvidia's compression is lossless.
And if there was lossy compression then you wont see washed out colours, there will be color artifacts and banding etc. The "washed out" image quality, is just
Nvidia's choice of not pushing the saturation and contrast to the limits like TVs in showrooms. A few minutes setting vibrance in the settings and it will match AMD
There is no such thing as lossless compression, its BS marketing speak, what they mean is "perceivably lossless" which depends on what the marketing guys deem as perception, i guarantee they take liberties with that definition.
