Hey Sam welcome to the obsession 
Most (if not all) plastics will yellow over time. You have probably have to replace the whole roof before you replace the window for a 2nd time.
There are plastic polish products that will clear up the window and keep it looking good for a number of years, but eventually it will become brittle and crack. If you do replace it make sure it is water sealed otherwise it will leak.
