In tpl_product_info_display.php I see the if

$display_price_top === true
$display_price_bottom === true

On the product page I see the latter one (inspecting the page I see id="productsPriceBottom-productPriceBottomPrice" class="productPriceBottomPrice")

I suppose there is a setting somewhere for it, but can't find it, what am I missing?

I can edit the template file to my likes, just curious to understand the functioning of it.
