The videos I've seen about the Frame all call out the front expansion port, which "Valve says ... offers a dual 2.5Gbps MIPI camera interface and also supports a one-lane Gen 4 PCIe data port for other peripherals."[1]
That's plenty to support color passthrough as a physical addon, which in turn makes me think that, like with the OLED Deck, we'll see a Frame with built-in color-passthrough later as a different premium SKU when/if they justify it.

I expect that a premium headset is in the works, but they probably didn't want to complicate what is effectively a console launch with multiple SKUs. They'll probably offer a 'Frame Pro' with wider FOV and better cameras a year or two down the line, possibly at the same time as the Steam Deck refresh we all know is coming.
