Chasing high ISO (for low light performance) is also means you are chasing dynamic range performance in bright light.
After all, shadow regions at ISO 100 could have essentially identical sensor illuminance as bright regions in when ISO 1600 is required for practical shutter times and, or apertures. In both cases sensor underexposure is similar and, more importantly, unavoidable.
The camera attributes that make using high ISO's practical in low light offer the same benefits for shadow regions in bright light.
