I have a 512 oled and got the jsaux screen protector, I put it on even before I turned it on(right when I unboxed it) but from what I can tell it looks really crispy and colors are amazing (I haven’t used an Oled screen for games prior) granted I’m used to 1440p at 27in monitor but I can’t really see any issues to the image quality so far everything looks great!
Best I can say is put on that screen protector before you turn it on and you’ll never know the difference:)
I got 3 Horizon Zero Dawn(never played but always wanted to) Terraria (Played like 3 times but lost touch with it) Bloodwash(I loved this game since I saw it on YouTube) I only just started my steam library but I got small games for my new OLED to play.
