Question about Fairphone 4

I would like to buy the Fairphone 4. The Grauer (605 CHF) has a low frequency of 60 Hz; the Grüne offers 240 Hz for a similar price. Is this a mistake - are both 240 Hz? - or does the Blue have less picture quality? Danke! --- I want to buy a Fairphone 4. The grey model (above, 605 CHF) would have a "Bildwiederholfrequenz" of 60Hz, while the green one has 240 Hz for the same price. In your opinion, is this a mistake on the specification sheet or does the grey one really have a worse visual quality? Thank you!
