Libra Colour Color question

I have a Libra Colour 2 and do enjoy it. Over the last couple of months in watching various videos and articles comparing the Libra Colour to the Kindle Colorsoft it seems like the color on the Kindle device is better, more true, and pronounced?

Anyway, I was curious if there were a consensus as to a CFA mode (in devmode) that comes close or is better looking than the colorsoft?

Are these modes safe to use in general?

Thanks
