Is this amount of noise in the bearings ok?

I have a carbon Canyon Grail I bought in 2023. from the beginning it felt a little noisy in the drivetrain compared to my old aluminum bike. Finally I got around to disassemble the chain to dive more into it and to my surprise I found that the ball bearings (?) of the crank were causing quite a bit of noise – see video. On my other bike I remembered this to be silent. Should I get this fixed or can I do it myself? I like to do all repairs on my own.
I’ve already applied grease to the bracket (? the round part which rotates between both pedal cranks) but it didn’t seem to help.

They sound very dry and not very round anymore.
