Yah you're correct. But in spots like - I triple barrel and am faced with a river jam, it's very difficult to know what villain is doing in this spot. The spot comes up pretty rarely and it's hard to tell if his range is more weighted to value or to bluffs, so without any concrete information GTO would default you on b/c approximately 40-45% of your triple barrel range (vs most river shove sizing in 100-110bb pots).

That being said, I think the safe average assumption is to assume the avg reg is probably weighted more towards value in this spot (as opposed to having a GTO distribution of value to bluffs), and thus should prob lean towards folding more often than GTO.
