How can I get a CRT-like curve effect?

I’m making a game that is inspired by older games and the computers that they are usually played on. On some of these games, they have a sort of “curve” where the screen where the player sees from is bulged and gives the effect that the game is being played on an older computer or CRT monitor.

I already have tried using the “Bulge” 2D layer effect, but this game is 3D and I can’t figure out how I could get that sort of effect.

For reference of what I’m trying to accomplish, here’s a game that has this effect:

It’s a bit hard to tell by the photo, but the game and the UI is a bit stretched around the edges

There’s a bulge effect for layers. Play round with the parameters on it to get the desired effect.

There is also a CRT effect which includes bulge, scan lines, and static
