Uber and Bolt apps works like normal. I don't know what is Grab.
The default camera lacks post-processing tricks, but you can install Google Camera if you like (shouldn't be a privacy concern here with limited permissions).

GrapheneOS Camera does have HDR+ and Night mode on Pixels along with HDRnet and EIS for videos. Pixel Camera has more features and more aggressive HDR+.
