One of the determiners of bifasciata, is that beside the dark line on the lateral line, there is another line/blotch above the lateral line. The "bi" in bifas, color is really not a significant ID determiner, because there are many location variants with differing amounts of red, or other colors.
Below is a rio chacamax variant, note the dark blotch above the lateral line stripe
And one of the main traits to look for in hartwegii (again not color), is an overbite, and since the front of the mouth is not visible in either shot, it would be very difficult, if not impossible to make that determination.
