No, the reasons Amber Heard is being ridiculed is complicated and not constructed to just one single reason.
there’s probably an element of yeh, at face value she is over dramatic and it’s entertaining. That’s a very small part of it though. Johnny Depp is a little ridiculous too. He’s had meandering rambling testimonies, he’s a grown man doodling and eating jelly beans at one of the most famous trials of the decade. He’s making jokes about “jars of dirt” when confronted with accusations about drug abuse. But he is exposed to vitriol for it? Not in the same way at all. This is an extremely harrowing trial, about very difficult and severe topics. It’s included sexual assault, violence, substance abuse. It’s not appropriate for either party to be ridiculed no matter how “ridiculous” they come across.
there’s also probably an element of public outrage at a sense of having been duped by Heard and championing perceived injustices against Depp
Heard fits into the stereotype of the “femme fatale” the attractive, overtly sexual, dangerous female (she literally gets typecast as this), so it’s easier to demonise her in this trial. She fits cleanly into the common public perception of what an “immoral” woman looks like.
there’s definitely an element of misogny - putting a woman who publicly caused the downfall of a powerful man, back in her place. The independent touched upon it in the below article. Again, it isn’t seeking to establish facts surrounding the trial and who may or may not be guilty of what - it’s specifically examining the social drives of the behaviour and the impact;

I actually think people trying to simplify this case into concepts like 'misogyny' is really reductive and suggests lots of people are unable to rationally and logically unpick the evidence themselves, removed from the man vs woman subtext the media keep trying to shove onto us to keep them aligned with the zeitgeist.
It's a person against another person, and the evidence so far suggests one of these people is lying more than the other.
