Sipo/utile would be my guess.
How about showing the edge to see if there maybe clues, as sipo/utile often has a fleck like beech,
which I've not seen on say meranti, nor sapelle.
Sapelle which has much tighter grain compared, to say meranti, (pores less deep)
i.e yer looking at sliced longitudinal pores when looking on the face of the timber, which you've shown,
and those gulleys (for want of a better word) look deeper than that,
But with nothing to refer off, hard to get an idea of the size of them, zoomed in may appear like meranti, zoomed out like sipo/utile or sapelle.
Hope that helps.
Tom
(edit: to add a little piccy of the fleck which sipo/utile often exhibits, which might be seen
if you planed the long edges, should it not be already visible because of finish,
and worth looking at both edges of that glued up panel)
