Pretty much. BCH bulls who find out about the supply issue have been assuming that it can't be that much of a big problem, that most people who wanted to sell must've done so by now anyway, and of course there's no way to tell how much supply is actually locked up. BCH bears are mostly irrelevant to the price since, unless they expected it to be worth enough to justify locking their BTC in less reputable exchanges during the fork, they can't actually sell yet. Anyone who isn't following the online discussions closely probably simply doesn't know about this - the news articles I've seen haven't mentioned that issue, and it took many hours for this information to even percolate through the discussions. Claims like "3rd largest cryptocurrency by market cap" have been a lot more prominent everywhere. (Also, if you want an idea of what BCH supporters are thinking right now, the front page r/btc is currently a good place to look.)
