Boost Mode on PlayStation 4 Pro doesn’t do much for PSVR
VR is already great though PlayStation 4 Pro, so it's not likely to improve much more.
The 4.5 update to PlayStation 4 Pro consoles added a Boost Mode feature, which was designed to offer more processing and GPU power to existing games that weren't going to update to the more capable "enhanced" mode. For normal PS4 games, this Boost Mode offers a slight stability bump to make things look consistently good throughout the experience. There was some hope this new feature was going to offer a little something extra to PlayStation VR games as well, our research suggests that's not going to happen.
