Here's what it says about the SE cameraIn Apple's Newsroom article, it mention's iPhone SE, then jumps right into iOS 13 talk about night mode in the sentence right after. This leads me to believe it would have the 11 camera.
"iPhone SE features the best single-camera system ever in an iPhone with a 12-megapixel f/1.8 aperture Wide camera, and uses the image signal processor and Neural Engine of A13 Bionic to unlock even more benefits of computational photography, including Portrait mode, all six Portrait Lighting effects and Depth Control.5 Using machine learning and monocular depth estimation, iPhone SE also takes stunning Portraits with the front camera. Next-generation Smart HDR comes to iPhone SE, intelligently re-lighting recognized subjects in a frame for more natural-looking images with stunning highlight and shadow details."
