Can do a close up picture on the wall? No idea what is this about?

I know. But need to see 'close up' then only we could tell what is it.
As i know, there is no such thing as 'gloss cement', it could be another layer of gloss finishes on top of cement.

It is ok, no need to apologize.
It depends on what kind of gloss material and how gloss you want. If just a layer of glossy sealer, that will not cost you much.

From the picture you show (Still not clear, as it is not a close up picture), i think you are referring to fair face concrete.
The fair face concrete material is not expensive, but it is difficult to do it in Malaysia due to the local weather. It is very hard to get a uniform colour of concrete as compare to those cold country, like Japan.
