Is stock ROM needed to make full use of Ultra Pixel camera?

In order to get the best quality of the "Ultra Pixel" camera in the M8 does one need to be running the stock ROM from Verizon? Do any of the ROMs available have the software/driver/app to make use of the camera to it's fullest extent (or at least as well as the stock ROM does)?

I really like the CyanogenMod v12.1. It is fast and stable. The camera however, seems a bit underwhelming. Would be great if there was a way to add in the HTC app/drivers for the camera to other ROMs such as CM.
