I'm having the same issue. The screenshots don't match the live view in Rhino. Even though it may seem minor, it is a big deal not being able to rely on the live view for accurate representation of the materials. I won't be able to present the live view and send screenshots that match. Please take a look at this.
I've attached a screenshot of the issue. Live view left / Export right
I'm on Enscape 3.4.1 +85781. I have also tried turning DLSS and the Denoiser off with no difference.
