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.

My understanding is that OVF Simulation presents a wider dynamic range, possibly based on HEIF as opposed to the Jpeg you get with the EVFs normally. So you should be able to see into the shadows better and the highlights transitions should be smoother. Neither of these views are therefore going to be ‘true’ to what you get when shooting RAW and post processing in your chosen application 😀

Yep, that's my understanding too (but I don't know what file format its trying to mimic). The fact that they will not be a true representation of the output is why I wouldn't expect it to ever have an exposure sim attached to it.

I don't think it's trying to mimic any file format. It's for the people who grew up with SLRs and DSLRs and rangefinder cameras.  The name suggests it's trying to mimic an optical viewfinder, which is great for people using studio flash,  or outdoors wearing sunglasses, or trying to recover an unnatural amount of shadow detail.
