@2raarchitecture I cannot really tell what you mean by 'final product'... as the preview window within the rendering dialog is showing Cinerender... and the other screenshot is your 3D window, which will typically use what used to be called the OpenGL surface...but is now called the 'hardware acceleration' surface now that Apple has moved to Metal from OpenGL.
The surface texture for a surface ... which may be part of a building material of course... can look entirely different for each of 'Basic Engine', 'Hardware acceleration', and 'Cineware by Maxon' ... the 3 choices for defining a surface in the attached screenshot. It is up to you to make sure that they look close enough to be your intention... unless the surface came with the default template in which case it is a bug to report to your local technical support.
For example - a surface might look like stone for 'Hardware acceleration' (what you see in the 3D window while working) and brick for 'Cineware' when rendered - although I cannot think of any reason anyone would want to do that.
At the bottom of the Surfaces dialog... there is a "Match Settings..." pop-out where you can approximate the basic and accelerated settings with the current Cineware ones or vice versa.
