Just like er...hatchetjob? I have a Flex. The most enviable property of the S5 is the lower minimum brightness.
PhoneArena, nice...a reviewer in the bottom 10% of accountability. Those are the greasiest, nastiest screens I have ever seen photographed. Ever. All the phones are canted at different angles, bits of grass intrude across a few of them. It looks like an Ebay listing for eight stolen cellphones....
It is hard to tell but the Note 3 looks good there too, and in some ways the iPhone 5S screen has what look like more accurate dark shades. You can really see the highly inaccurate hue shifting on the S5 also, coupled with the oversaturation it is clearly readable but not pleasant to look at. If the photos had been taken with even a grain of skill, they wouldn't be a waste of time and opportunity.
The S5 does have an accomplished panel and a very good ambient light compensator, but even in those awful photos you can see that there is a price for what legibility it achieves.
