This just depends which plane you get. They all have new and old planes, you can get unlucky on any airline.

The entertainment system on the seat backs was Linux in a reboot loop.
JAL/ANA have very new planes with cool entertainment systems, but they also fly their older planes on some routes with a bunch of stuff that looks like it's powered by VCR.
To your question: they probably don't for their major international flights.
