I am sorry but that too is the wrong attitude. If that is the case then why bother with an IFE at all? And then, why advertise your IFE offerings whilst trying to drown out the competitor's offerings. Whether or not the OP is entitled to compensation is certainly debatable, but by today's service standards, it is also absoultely within the customer's expectation to be entertained while flying. Period.

If the IFE isn't working, they should make an attempt to solve it the best of their abilities. Usually in semi filled flights, this is not an issue. Either ways, the OP certainly has something to gripe about, especially on such a long journey, regardless of whether he was upgraded to J or was a paying J pax.
