In search of a brick wall…

Obviously I can open small portion and check it myself, but my question is relatively easy to answer, so, I am going to ask here first:

What kind of wall is the wall that runs above main beam and divides “wider” rooms and narrow “small” rooms on the same side as stairs.

I have really bad sheetrock walls in my “smaller” room. I like an idea of painted brick wall instead. It is an interior partition, the other side of the wall (bigger bedroom) has nice old plaster, so, insulation is not a problem. Also, I will gain about 4 inches in small narrow room.

but I am not sure that this wall is brick! It looks like it should be, but I am not sure.
