iPhone Air Air and 17 pro show different appearance fir same web page

[Zapdoc]

Have both air and 17 pro deciding which to keep
Just noticed that on air Dpreview home screen is black background while on pro it’s black. All settings are same on each phone and same apple ID

How can this be ?
both look great but liking the black background better but white on pro is very white

Both display options is set to dark background on phone settings

thanks

not helping me decide between the two any easier !!
