M4 Macbook Pro Resolution support

I have a Samsung CRG9 ultrawide monitor. It's capable of 5120x1440 @ 120Hz over DisplayPort 1.4. Will the new M4 MacBook Pro's be able drive this at 120Hz over Thunderbolt 5? It seems the bandwidth is certainly there, but the aspect ratio is an oddball and I have my fingers crossed it's natively supported.
