How to output the highest quality photoreal images

I’m trying to take a photo real screenshot using ue4. Which is better, the high res screenshot with the viewport as the Game view or the rendering of the video with the cine camera?
I’m using raytracing.
I tried both raytracing (raster effect + path tracing) and Path Tracing for screenshots in the viewport.
As a result, the Path Tracing image was dimmed in color. Is it possible to use Path Tracing for expressions like raytracing?
