Most if put side-by-side will look slightly different, sadly is normal on almost all devices as they never care for the customers a single bit when it comes to LCD...
You will only get pretty close results on professional screens which are calibrated to work with pictures, movies or get a good screen and pay to be professionally calibrated...
Most TVs also have different panels in the same exact model of TV and sadly all the customer can do is pray to be lucky in getting the best panel.
On phones is also a joke, some even high end phones have very huge difference in screen quality sometimes like for some it's reddish, others blue, others yellow on the same exact model...
My Switch doesn't look bad, but I also would prefer to put a bit more blue in the white calibration as mine is also a bit warm, hope they could ever add that feature at some point like on atmosphere emunand CFW...
