Yes there are massive differences, first of all there are 40pin and 32pin original gbas with the 40pin screens being the original brighter, better and more power hungry. There are also differences between sharp and panasonic screens.

Beyond that I have a ags-001 gba with a DOGSHIT screen, compared to my original 40pin gba is it darker, the gamma is way lower so its black crushed, and the gamut is way smaller so red appears like orange. There are big differences.

Nintendo screen quality and consistency has never been good, just look at the whole 3ds tn vs ips where the ips has the wrong gamma lmao (2.4 rather than 2.2)

I have talked to two people however whos ags-001 screen is as good as the 40pin supposedly, and it should be better if so because the ags screen have a diffuser layer which stops the rainbowing stuff that happens in direct sunlight on the agb screen (seen in picture attatched)

Nintendo screen consistency is a crazy rabbit hole lmao.
