1. Check Ur contrast levels and reading mode settings.
2. Yes benchmarks will raise the temp but it should cool down fast. Btw what was the room temp at that time

Maybe if contrast and reading mode settings are same, ucan look at both the phones together at maximum brightness or comparative brightness and then judge. No harm in showing to service centre if I still feel Ur display is inferior
I am no expert about LCD panels and cannot comment on what variation is acceptable.

I have the feeling that my dispay has the same dull color. Haven't compared it to any other poco yet, but colors seem to be washed out, comparing for example with a mi5 or an iphone.
You can check the display manufacturer and see if both have the same panel installed

I have Tianma if i remember correctly. I am on LineageOS and cannot check now but I'm 99% sure.
You can check by going to Settings > 'About Phone' > Tap 'Kernel Version' a few times
Select version info and it will display a bunch of info, including manufacturer, in 'LCD'.

It happens a lot with cheap displays when doing screen calibration, it signals bad QC but that's it. it's hard to find two displays that are 100% identical even more noticeable with cheaper ones, I say it indicates nothing but an improperly calibrated screen at the factory, if it doesn't bother you then you have nothing to worry about. Otherwise, I suggest that you return it.

Press kernel version 7 times which will start CIT in there choose nr 1. Check Version info.
Do that on both phones and check the "lcm information" it's in the bottom, might be reason to why picture is different between the two.
Different lcd panels maybe?
Check picture, that is my version which is first generation pocophone F1 with 128gb storage.

If both phones have identical parts than yes there is definitely something wrong with quality control at xiaomi.
Check Version and see, decide your self if you can live with the "issue" if yours looks bad, only you can be the judge of it being bad or not.
