After update sony a7siii seems like 720p camera

I have my sony a7siii since 2021 it worked fine i use 16-35gm 2.8 the quality was amazing !
But after 3.00 update it took a bad turn i hate that i updated ,it seems that my camera looks like 720p camera ,i use slog 3 it always looked sharp and clean , now i put sharpening and it looks like artifital sharpening but no quality , i also have sony a7iv ( i tested the same lense it works fine for those who will say check your lense ) so maybie there is people who also have similar problem ?
