I've also read that "m0*gamma" isn't "real" mass. I've also read that
time dilation is not "real". Both statements, as written, are
nonsensicle -- they are both meaningless.
To make them sensible statements you first must define "real".
Can you do that?
If you can, then you'll also be able to say definitively whether either
of those effects is "real".
But if you can't define "real" then any question about whether something
is "real" is meaningless.
