That would have been my take too. Now, given that, and given that
the flame isn't visible, is a blech needed altogether, or is ketima
effectively done by the mechanics of how the food is heated?

IOW, is ketimah covering the flame, or not having a flame to see?

My take from the gemara is in the case where there is no flame to see as
too low or high and therefore no chance of panic to stoke it, requiring
any form of blech is already above the minimum of the din.
