help me choose between this two

I'm was looking for better display phone in budget and i found this too. I just want suggestions regarding that. What's better 8 bit 6.43" fluid amoled full hd+ 410 ppi display with 90hz of refresh rate or 10 bit 6.67" amoled full hd+ 393 ppi display with 90hz of refresh rate. I prefer good quality display because i consume High definition media. Please help me choose between this two.
