I’ve used a setup similar to what is used in a scene here: [Free scene] Loft interior design by @Holi_Home (it’s free and it is awesome!) I don’t remember the exact values I’ve used and I don’t have acces to my pc right now to check it but I what gave the scene this specific high contrast look was high gloss value set to 100. HDRi used in the scene was this one: https://hdrihaven.com/hdri/?h=kloetzle_blei I will post a screen with my setup within few days 
Hope I’ve helped!
