The model year of an iMac is available at Apple menu > About This Mac.
A late 2015 iMac can be upgraded to the latest version of Monterey macOS 12 but no later.
A 2017 iMac can be upgraded to the latest version of Ventura macOS 13 but no later.
For all of the above, see instructions in: How to download and install macOS - Apple Support
