For me it was noticeable difference, as normal AMOLED's are worse in resolution the RGB feels blurry instead. Not sure how to explain it, you can try confirming if you have huaxing through the dial when you input the *#*#284#*#* which creates that bug file .zip
Unzip the file, there might be another zip file with the same name .zip, unzip that one too and open "dumpstate_board.txt" then try search "TIANMA" if that is unsuccessful then try "K9 42 02" if it found these numbers, then it is Huaxing.
If it isn't clear what I said I can try explain it better
Btw: yes I started doing just eat recently
