As anyone can see, the flight OP is taking is operated by a Boeing 777-300 with full in-flight entertainment with 9" seat-back mounted screens in Economy class. I think on a travel forum any advice given should be current otherwise what's the point.
The point that you may not have noticed is that PAL changes planes to suit their needs so what is showing now might not be the plane on the day
airlines are not uniform and have different standards on different routes. Once I took a Royal Jordanian to Bangkok via Amman. London-Amman it was OK - it was like one of the decent Gulf airlines, but Amman-Bangkok - not one of their top-notch destinations, everything went sharply downhill. PAL are going to be the same, like one airllne when they carry Americans from LA to Manila, and another airline completely when they are carrying OFW's back from their two years on the Gulf.
