The two are the exact same thing. What you are actually talking about (well,
want to talk about) are color spaces. -- So to answer your question: POV-Ray
uses a (practically) unlimited linear RGB color space internally.

Do you even understand what you are claiming??? - It should be obvious that
such a statement cannot and would not be in any standard because a standard
is the formal definition of an agreement between several parties, not the
description of an absolute truth.

I won't even go into details of your claims about CCDs, which demonstrate a
complete lack of understanding of the functioning of a CCD (hint: the "bits"
come from an A/D conversion). Or the implementation detail of most digital
camera "raw" formats.

Either way, this has nothing to do in any way with how POV-Ray internally
handled colors. It has (a little bit) to do with reading and writing image
formats supported by POV-Ray. I think it is sufficient to say that the
handling of image formats by POV-Ray is (mostly) correct within the scope of
the libraries that it uses to read those formats, which does include gamma
correction and color space conversions (for HDR formats).
