I have not noticed a significant change yet though only moved to the stable One UI 5.0 today. It is also good practice to either use the Repair Apps option in Recovery Mode or run the Galaxy Apps Booster via Good Guardians. However the AI will likely take a bit of time to fully kick in.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
