Thinning an application without @ 3x images and when some images are jpg

Question

For the upcoming update of one of my applications, I packed all the image resources into asset directories.

However, at the moment I do not have the @ 3x version for most of my images. I checked with the simulator and on the iPhone version 6 Plus @ 2x.

I am not opposed to this behavior for two reasons:

• The result is good enough for the images I use
• Only 50% of my users use iOS 9. If I add @ 3x images, the size of my application will increase dramatically for those on an older OS.

Although the images load correctly in Simulator for iPhone 6 plus, I'm a little worried about what happens when I archive my application. In particular, I'm afraid that with the App Thinning iPhone 6 Plus, users will get the application without any images :)

So, I have two questions:

• If I did not provide an @ 3x image, will @ 2x be added on the iPhone 6 plus after my update appears on the App Store?
• Am I still benefiting from the Thinning app, as users with @ 2x and @ 3x displays will not upload @ 1x images (and vice versa)? Or will the Thinning application not work in this case, and users will receive the same assets regardless of the screen of their device?
