I've been thinking about this more...
Thing is OP, only you know if he had any kind of point. You say your pics were only a couple of weeks old....but were they all shoulders up?
I'd never date a bald man. And I don't like 6 packs. Nothing wrong with admitting that, it's my preference. Muscles are a turn off in my eyes. I like the dad bod 
so literally, if someone had a pic that didn't show they were bald, and had become suddenly buff, I would be royally pissed off to discover this in person if I had been misled with their pictures otherwise and they hadn't been honest with me. I know a lot of woman would be thrilled to see someone akin to Jason Statham rock up, but not me at all. I'd be annoyed that my time had been wasted.
So, honestly, look at your photos. Do they make you appear much slimmer/bigger/taller/shorter in enough of a manner that someone would feel you had misrepresented yourself? Even things like a picture of you with a cropped Bob 6 months ago, if you've got long hair now. Or vice versa. Yes it's superficial. But in the real world, people do of course have preferences.
And again, on the video chat, was this just your head?
I still maintain he's said something because you plonked him openly into the friend zone. Men hate being rejected and some have to be snarky than accept it. But I doubt it will be the first time you hear this, if your real life self doesn't match what you're projecting.
It sort of says, this is who you think you're meeting, and I decided on your behalf that you wouldn't mind when a completely different person turned up. And kind of suggests you already think no one wants meet the real you, or you would present the "real you" right from the start, which isn't a good way to come across.
I think there's a big difference between posting pics that make the best of you, and posting pics that hide most of you. If a guy turned up, had claimed to be 38, but was 41, and to be fair looked good for his age, then I'd be a bit wary of his general honesty, but it wouldn't be a deal breaker and I'd explore a second date. If a guy who'd posted pictures of him age 38, and turned up aged 58, looking like his former self's Dad, I'd be out of there. Because it's a completely different level of knowingly misrepresenting, and the attitude that it's ok to mislead and waste my time. That's why I'd walk out, more than the genuine fact he was 58.
Be honest with yourself, and the people you're talking with. Some are in love with your curves, some aren't. If you're representing yourself as a slimmer person than you are, you're doing yourself a disservice by missing out on all the guys who adore a curvy woman.
