I downloaded a 200 MB app over Cellular data today. Then I tried another 300 MB app, with no warnings whatsoever, and the download completed successfully. Final I tried a 1.2 GB download which failed with the popup warning message.
I understand that App Slicing has appeared since iOS 9. The actual download size is different from the indicated size. But after downloading, I checked in Setting app → General → → iPhone Storage, and the two apps are over 150 MB(198 MB and 211 MB). And they are new download not updates.
Is the size displayed incorrectly or has the upper cap for downloading new apps over Cellular data changed?
PS:I downloaded that two app before but uninstalled it.
Another assumption is that the downloaded content is actually less than 150 MB but there is a process of decompression?

No. The upper cap for downloading new apps over mobile data connection is unchanged from Apple. It's still at 150 MB. There is no official word from Apple after last revising the upper cap to 150 MB. This is the warning that I get (Indian App Store, accessing over 3G data connection in India) when attempting to download an app of size 2 GB.
However, the related Apple support document, If you can’t download or update apps, or if apps get stuck mentions the following in fine print.
The restriction is in place not due to some limitations in iOS, but to guard the mobile service providers network against congestions. From the statement it appears that some service providers must have worked with Apple and are offering a higher download size cap.
