iPhone X with different hue / True Tone

I have been struggling hard to keep the best iPhone X and so far two iPhone Xs I got have different hue or you can call it different True Tone when turned on. So I will need help in deciding which one is more accurate, correct or closer to intended tone? Any ideas, information or insights will be highly appreciated. I was in fact thinking to buy another one to further inspect. I also compared with the ones at the Apple store and they all have different variations.

Please note that both phones have identical setting and nothing is turned on in Accessibility settings.

Regards,

Rae
