The most impressive part of Control's RT (on PC at least) was that it very much applied to (most) dynamic objects - and it features a TON of dynamic destruction.
The "office building" setting meant resticted areas, sure, but it features TONS of reflections - especially transparent reflections (which are practically impossible to decently approximate with screen space techniques).
Oh, and: The Northlight Engine already did more than most other engines at the time to get "90% there" with a ton of hybrid techniques, not least being one of the pioneers regarding realtime software GI.
