Hi Lucy, because Skybox is running through SteamVR, I imagine this issue is not specific to the PSVR 2. It can probably be reproduced on any compatible SteamVR headset with OLED displays.
I believe it is just the filter of the ambient light setting not making the void skybox texture dark enough. I've actually noticed that the Moon environment when its ambient light is set to 0 is actually a pure black! With this discovery I am able to enjoy what I am watching in VR.
If you or one of the other devs on the Skybox team took an eye dropper tool to the void environment texture with the ambient light set to 0, I'd be curious to see what colour you get. From an unedited screenshot I get a colour hex of #020202 just past the edges of the screen and a colour hex of #010101 just above the screen. This tracks because when the ambient light is not set to 0 you can see the void texture looking down is a light gray and gradually turns into space as you look up in VR.
