I've never used the 21:9 option on my OPPO, I just use the lens memory and zoom for different aspect ratios. Would I be better off to use the 21:9 on the OPPO instead of the lens memory? Would I have better resolution if I did it that way? I also use custom curves as opposed to the functions on the OPPO. Maybe I should play around with that also. Equipment is in my signature. Sorry I'm kind of a noob when it comes to this stuff.
