All profiles by Maurizio are of the 'creative' type. It means that they are imitating some specific 'creative style' of some particular camera, or are trying to create some other specific look.
None of his profiles really produce technically correct neutral colours/tones. The name 'Standard' simply means that the profile attempts to look like the camera's internal 'Standard' style.
Of his 'Standard' profile for the a55 I must say that it's just a simple single-illuminant profile as it is obvious from its 28kB size, so its low-K performance is very poor. It has badly oversaturated and darkened greens, pinks turned into yellows, reds are overbrightened and burnt-out... Very bad.
The daylight performance is better, but there you get the skies shifted towards turquoise and also oversaturated, which means that the sky blue is readily blooming into the clouds white.
Generally, I'd say that using Maurizio's profiles is only justifiable if you need that very particular look they deliver into some specific image; and they are not the general-purpose profiles.
My 'Deep' profile produces a really standard response that may then be modified with custom HSL adjustments or presets. I prefer this approach because introducing too strong adjustments directly into the camera profile leads to limiting the tonal resolution too early in the processing which in turn limits the further adjustments' available latitude.
