After last upgrade max brightness is low on OLED screen

Hello,
I have Dell Precision 5540 with OLED screen and (of course) Arch with Wayland + Sway.
Before last upgrade I had mapped brightness control keys to forked redshift. It worked pretty much great but after last upgrade I can see that max brightness is very low. I can see brightness is changeable, but max brightness is very low.
I also tried gammastep and same issue, brightness=1.0 is very low.

Do you think what it could be? Like this I have to use monitors only as in sunny room I cannot see anything on my laptop.

Thanks for help!

So it's probably that linux-oled was merged to Kernel 5.12 somehow.
But there is no information about that...so I need to downgrade kernel...
