Fenix 7X does the solar ring shade reflection depends of Sapphire glass or not ?

The solars ring of Fenix7 looks uniform red/brown colour on non sapphire version, when sapphire version has green or yellow  shades on different angles and  reflections are not uniform, because some sides of the solar ring has different colour reflections in same time ( like left side could be more green and the opposite side could be yellow in the same time). 

Is it true ?

Where I can see the comparison between sapphire and non sapphire? 

Thx
