There are different modes you can select on Samsung phones if you don't like your colors as vibrant. Samsung also doesn't over saturate colors like they used to. Samsung's displays have been the highest rated displays for the last couple of years.Hmm, best re-evaluate what you know!
Samsung displays might look better. But the colours are just so artificially inflated to make it all look vibrant. It's like something off a cartoon. Quite apt, seeing as they're running operating systems like "Chocolate Biscuit" and "Gumdrop Forest". Side to side, you'd be forgiven for thinking the Samsung ones stand out more, because they do. However, this isn't necessarily a good thing.
Apple concentrate on stuff I'd say is more important. Colour balance. Accurate representation of colours. It's the same with their Macs. The balance on their displays are absolutely gorgeous. Yet somebody will point to an HP laptop with a 4K display and say "oh, that's a better display". Based on brightness, or just specs on paper with the amount of pixels.
You get a lot of people judging from numbers alone. Mainly why a lot of Samsung fans perspire about the hardware specs, without knowing or appreciating what effect they have in real-world scenarios. More RAM. More cores. More megahertz. More PPI. More megapixels. The reality is completely different.
The problem I see with people talking crap about Android, Samsung, etc. is that they base their arguments on very old facts. I still see people talk about how laggy Android is or how much it crashes when apps on iOS were proven to crash more than on Android a couple of years ago. There's no point in arguing with those people because they had or used an Android phone a long time ago and their opinions are stuck in 2010.
