As i am always curious about new sources i had a look and a trial with Idagio short after start. Good idea, but....
The editorial part, which could be (and in the companies eyes is) outstanding, new and what so on isn't. It's kind of boring. Sorry. Take a look at the BBC Music magazine and you have more and extensive recommendations.
That it is "only" 44,1/16 would not be an issue for me.
I checked cross with Qobuz for some historical recordings. Especially some Callas live gems. No differences. Both have the recordings or both have not.
Result for me: Not worth the relatively high price.
