Just spent a week with an R3 and honestly couldn't find a use for the feature. I'm sure there was more to it, but when I enabled it it just felt like a brighter display. I only gave it a few minutes of use before moving on. As the other poster stated, the standard exposure sim is way more useful and I found I was missing more perfect exposures with OVF Assist on.
I wouldn't expect to see this feature combined with Exposure Sim in the future either. I guess the idea is to give you a higher dynamic range to see what the shadows "could" look like to an extent. Because the normal Exposure Sim is a direct representation of the actual image (in a lower dynamic range) adding Exposure Sim to the OVF Assist would not be representative of the image, so its likely disabled on purpose to avoid an inaccurate representation on the image.
IMO, this one is like Dual Pixel RAW, interesting feature, but no real use.
The real world use case is when shooting with flash against a bright background such as a window or at sunset and finding that your subject is a complete silhouette in the viewfinder and you cannot see their face. This makes timing your shots and even focusing accurately very difficult, and is a fairly common occurrence for me as a wedding photographer.
At least, I really hope it fixes that issue. I don’t have an R3 and I didn’t see anyone talking about that use case in the reviews. But hopefully if it’s going to be in the R7/10 they might add it to the R5 via firmware.
