If the startup screen allows you to, say, launch an "Open File/Project/Folder" dialog or load one of the recently-worked-on items, but won't let you do anything meaningful - then yes, Yay.
It's quite realistic to load that kind of UI in a lot less time than the "meat" of an app is usable. I would take 0.4 seconds for that and 2.2 for the whole app over 1.2 for the whole app - any day of the week.
