Someone else said the actual OLED doesn't support it. I never paid attention because I talked myself out of needing one, but if that's the case you obviously wouldn't see it on the deck screen.
I think you'd run into the limitations of render quality for most stuff 3D, though. There might be 2D games that play with it, and I'm guessing there are demo videos. I know my first (non-HDR) OLED I enjoyed trying some OLED demo clips out to really see what it could do.

Sorry I should have been more clear. I’m using the steam deck oled with the regular display, not an external display.
