That’s fine. It’s a preference thing whether you like it or not. Warmer things you can taste better though. For example, usually good sake is drank warm and bad sake is drank cold.
Personally, saisons I like to be warmer. It really helps their smell and flavor come through. I don’t mean warm though, just warmer. Around room temperature or so.
The one day ones are fairly pointless, but 40 is good. Give it a month and if nothing changes then you have a bit more time to try to extend it.
