Would the 60/40 ratio fit 2D category then (seems it could be something akin to matte painting)?
EDIT:
Actually, your answer made more questions for me 
1). So basically it's best if static render (A/final image) is done in marmoset? Or can it be done in raytracer renderer such as keyshot for high quality?
2). Most important question, if it's allowed for static final image to be rendered in raytracer, how much of importance for juding is flyby/marmoset, how much is it important for it to be close to final image in terms of appearance? What exactly judges are going to look for in marmoset?
The difference in quality and production time between raytracer and realtime is vast and I would like to be clear of what's yes and no in terms of judging. If marmoset can be used as kind of preview. To see how scene/world is built. And whether appearance (texture/lighting quality) in both marmoset/flyby video is important or not.
Not going to lie, marmoset is a bit troublesome aspect to me because of issues with my ancient gpu and requirement to make models/textures in reasonable sizes and polygon counts, unwrapping and so on. I'm still thinking of optimal workflow strategy. Perhaps flyby/turntable video can be low quality? (480p or 720p, replace complex materials with simple diffuse materials to cut down rendering time of frames etc.?)
