|The Color Skopar (with or without an X, that doesn't make a difference) 50/2,8 is a Tessar construction, four lenses in three groups, and it owns the advantages and disadvantages of this construction.
In the centre it is sharp and contrasty from f/2,8, both on FF and on APS.
The edges are a different thing. At f/2,8 they are not usable, and you have to stop down to f/5,6 or f/8 for sharp edges.
I don't know the Domiplan, so I can't compare.
I don't use the Color Skopar often, but only because I normally use the Rodenstock Ysarex 50/2,8, also a Tessar construction, whose Bokeh I like better. The sharpness of the two is the same.
Here are some photos taken with the color skopar.
That was with f/5,6 (probably) or f/8.
Taken with f/5,6.
This is wide open f/2,8 with the focus on the top of the gate.
Here is a detail from that photo (the centre; the edges are not usable):
