The user agent of safari is
Mozilla/5.0 (iPhone; CPU iPhone OS 17_1_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.1.1 Mobile/15E148 Safari/604.1
Whereas the default user agent of Orion on ios is
Mozilla/5.0 (iPhone; CPU iPhone OS 17_1 like Mac OS X) AppleWebKit/86126.96.36.199.11 (KHTML, like Gecko) Version/17.1 Mobile/15E148 Safari/86188.8.131.52.11
I do not know whether this is bug or intended, but this would definitely make it stand out.
However, I would suggest keeping it same as safari to reduce chances of using user agent for fingerprinting
