In my experience the default gcam struggles with landscape photos making the grass look very strange when used on a large screen as a desktop wallpaper. I also find the zoomed in detail pretty poor on the newest update compared to when I first bought the 6a.
I found this gcam mod from MWP called "Gcam_8.4.300_beta6" that seems to fix both of those problems. The only bug I found with it is sometimes the image looks very blue or very orange, but this goes away after restarting the app.
The only settings that I changed from default were in Settings -> Advanced -> Super res zoom (ON) and also Settings -> Advanced -> Lib-patcher -> Custom Libs (MWP-NoiC).
I find that Custom Libs setting to have the best detail from my limited testing side by side but it does make the photo slightly less vibrant than the default google camera app.

I also tried the new beta7 but it crash looped for me so I went back to the beta6.
