The Seahawks were 3 -3 against backups in the 2020/2021 Seasons. But two of those losses came against Colt McCoy (as both a Giant and Cardinal).
Also, I feel like the "make the backup QB look like an All Pro" sentiment gets overblown around here. From 2017-2022 this team won about 60% of games which isn't that different from the win rate against backups.
I agree, that in actuality, we perform just about the same against backups as

League wide, backups win just 33% of their starts (I wish I could find the graphic, but I saw it last year, so I ask that you trust me). The 40% success rate that you quoted would qualify as a poor track record, plus as you indicated, our W/L record over that period of time is over .500, meaning that you would expect a backup to perform less than average against us, or less than 33%.
But my point wasn't to argue the winning percentage of backup QB's. It was that we shouldn't be assuming that our odds have improved based on the news that Andy Dalton will start the game Sunday.
